qcacld-3.0: Reject Vdev trans when driver in unloading/recovering

Przeglądaj źródła 
Previously vdev trans will be rejected if psoc in trans. but
it causes issue when __hdd_psoc_idle_shutdown is in psoc trans,
if ifconfig comes here, the ifconfig will fail.

Add checking if psoc trans in driver recovering and unloading,
if yes, it will be safe to reject vdev trans, otherwise, we should
let vdev trans waiting for psoc trans.

At the same time, we also need to make sure driver state has been
set before psoc trans when unloading.
