qcacld-3.0: Free active RRM current req on STA roaming

Scan on channels triggered as part of active mode RRM
beacon report request fails on receiving roaming
indication from firmware due to get_session_id_from_bssid
failure. So current req in RRM PE context will not be freed
and as a result all subsequent beacon report requests will
fail.

Fix is to free current req in RRM PE context on scan
req failure due to STA roaming to a different AP.
