qcacld-3.0: Debug the reason for recovery during driver unload

During the driver unload whenever the recovery is triggered in
the current implementation the request is silently dropped, this
is resulting issues in other areas during the driver which is making
it harder to debug the issue.

Trigger system panic to debug the reason for recovery during the
driver unload.
