Call cqhci_crypto_recovery_finish() method during cqhci
enable in order to reprogram all keys into ice.
This is needed to cover the case of mmc reset followed
by cqhci recovery, which leads to all keys being cleared.
This causes an invalid crypto config error during
read/write of data after recovery is done.
Test: Verfied by storage team as part of mmc reset and
cqhci recovery testing.

In the case of a linkdown during pm_suspend, the
pci_saved_state during enumeration(default_state) is
used to restore config space. But this state is freed up
during pm_resume as part of pm_load_and_free_saved_state.
And if this state (default_state) is used again in case
of another linkdown, this leads to use after free.
Fix this by using a copy of the default_state instead
of the original copy for restoring config space incase
of a linkdown.

A potential use after free can occur in _vm_unmap_aliases where an already
freed vmap_area could be accessed, Consider the following scenario:
Process 1 Process 2
__vm_unmap_aliases __vm_unmap_aliases
purge_fragmented_blocks_allcpus rcu_read_lock()
rcu_read_lock()
list_del_rcu(&vb->free_list)
list_for_each_entry_rcu(vb .. )
__purge_vmap_area_lazy
kmem_cache_free(va)
va_start = vb->va->va_start
Here Process 1 is in purge path and it does list_del_rcu on vmap_block and
later frees the vmap_area, since Process 2 was holding the rcu lock at
this time vmap_block will still be present in and Process 2 accesse it and
thereby it tries to access vmap_area of that vmap_block which was already
freed by Process 1 and this results in use after free.
Fix this by adding a check for vb->dirty before accessing vmap_area
structure since vb->dirty will be set to VMAP_BBMAP_BITS in purge path
checking for this will prevent the use after free.

When changing USB speed via sysfs, the device might utilize the
idle time between DISCONNECT and CONNECT events and enter suspend.
As a result the pending CONNECT might get delayed thus pushing USB
enumeration during the next resume. Avoid this by not releasing the
wakeup source when usb restart is in progress.

When qdss open and close are called back to back at a high rate,
connect_work that gets queued in qdss open can execute after
qdss close. For qdss HW path the connect work that gets scheduled
as part of the next qdss open results in ep config failure as the
ep is already configured during previous connect work. Now before
queuing the request if there is a qdss close it would reset the dbm
ep configuration thus routing this request via software path instead
of dbm path. The subsequent dequeue would lead to a NULL pointer
dereference of completion callback. Fix this by flushing connect_work
as part of qdss close for graceful termination.

During D3hot, we are explicitly blocking L1 state by setting
REQ_EXIT_L1 bit of PM_CTRL register. If we transitioning back to D0
from D3 (without D3cold), REQ_EXIT_L1 bit won't get cleared. And
L1 would get blocked till next D3cold. Clear this explicitly during
D0 to avoid this scenario.
