qcacld-3.0: Add and use API to check FW Down indication bit during probe

Browse Source 
When commands to Firmware fail during probe due to Firmware being down, in
most cases QDF_BUGs are hit, not allowing re-probing to take place. A new
API is defined to check if the failure is due to Firmware being down or not.
If so, return error gracefully allowing re-probing to take place
