qcacld-3.0: Check for fw down before reinit complete

Currently reinit resets the recovery in progress flag when
reinit is successul. It may happen that after initial handshake
with FW during reinit, FW crashes and send the FW down indication
to the driver. Driver sets the recovery flag in FW down but it gets
reset on the successul reinit.
Now on subsequent shutdown, driver crashes as recovery flag is
reset by last reinit.

Check for fw down to reset the recovery flag on reinit completion
