Sourav Mohapatra 5e4000bde8 qcacld-3.0: Remove validate_context check from wlan_resume 
Presently, there is a very narrow race condition that causes
scheduler_thread to remain in a suspended state for undefined period of
time. The race condition occuers between idle_psoc_timeout and
wlan_hdd_cfg80211_resume_wlan.

As a part of idle_psoc_timeout, the driver calls hdd_wlan_stop_modules
that sets the flag "stop_module_in_progress" and checks if driver is in
suspended state. If yes, it resets the flag and returns. But in the case
of a race condition, before this reset and return is carried out,
wlan_hdd_cfg80211_resume_wlan is invoked. The validate_context inside
the resume function fails due to the above mentioned flag being set. As
a result, resume fails and the driver stays in suspended state. This
causes the driver to enter a infinite loop of stop_modules not being
successful.

To close this small window of contention, remove the validate_context
check. hdd_ctx is always guranteed to be valid and also DSC takes
care of synchronizing the operation, thus the check is redundant.
