qcacld-3.0: Fix deadlock in driver probe failure

Wlan driver probe callback is called in
CNSS work thread(cnss_driver_event_work in
cnss_powerup).
In case the hdd_wlan_startup failed, and
doing cleanup in hdd_wlan_stop_modules,
the later will call and pending on pld_power_off
to wait for cnss completion. So, deadlock
happended.

Don't need to call power_down because we are in
(driver loading).

Fix by check driver loading state to skip
power_down.
