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.
