qcacld-3.0: Assert early on to enable dump info collection

Browse source 
Presently, in the host initiated recovery the handler checks whether
the support for recovery is enabled via the ini or triggers the panic.
Whenever the panic is triggered the irq's will be disabled,
this results in some targets not able to collect the important
MHI, PCI information on what caused the issue to root cause the issue.

So, for different targets check the ini at different places. In this
case, move PCI based check to the start.
