With the recovery changes, if modem is brought down without FW
ready but WLAN driver is registered then shutdown call back is
called. This causes stability issue.
Make sure not call the shutdown call back if driver is not
registered. Also listening for PD notifications are enough even
for Subsystem restart so changing the quirks to take care of it.

Race condition observed during driver probe/remove and
suspend/resume because suspend/resume is not serialized
to work queue. Fix this problem by holding a wake lock
during wlan driver probe/remove to prevent system
suspend/resume.
