qcacld-3.0: Reset uOsRequestedHandoff when reassoc fails

qcacld-2.0 to qcacld-3.0 propagation

uOsRequestedHandoff is not reset in many scenarios after reassoc
fails/timeout. Due to this if the next connect request initiate
scan for ssid to find the AP in local cache, the scan for ssid
complete handler think that OS requested handoff is in progress
and returns without initiating the connect or connect failure.
Thus the HDD remains in connecting state and after that scans
fails.

To fix this reset uOsRequestedHandoff whenever reassoc fails
