qcacld-3.0: Fix HDD reassociate fail case for LFR2.0

Browse source 
If station connect with infrastructure network, might connect to AP
different with the hint bssid, if reassociate command issued, it will
invoke hdd_reassoc(). It might bring down connected station without
bring down vdev of the LFR2.0 path if the process of scanning for ssid
failed.

Add back logic of checking uOsRequestedHandoff and route to correct
LFR2.0 roaming path.
