qcacld-3.0: Return the cached rssi in get_station during roaming

qcacld-2.0 to qcacld-3.0 propagation

Currently, if get_station is called during roaming, host does
not send the correct rssi.Because of this, supplicant reports
very low rssi to upper layer and handover happens to cellular.
To mitigate this issue, send the cached rssi when get_station
is queried during roaming.
