qcacld-3.0: Scanning failed due to reassociation is in progress

If driver gets connect command with bssid hint, fast reassoc command
is sent to FW and roaming_in_progress is set to 1. In another thread
while disconnecting, vdev down is sent to FW. As vdev is down fast
reassoc command fails in FW and host will not get response, so
roaming_in_progress will never set to 0.

To address this issue, set roaming_in_progress to 0 after disconnection.
