qcacld-3.0: Fill STATION_INFO_SIGNAL when returning cached value to upperlayer
qcacld-2.0 to qcacld-3.0 propogation.
When there is an get_station request from the upper layer during roaming,
the driver returns a cached rssi value but it dosent set the "sinfo->filled"
(station_info_flags) bit flag for the NL80211_STA_INFO_SIGNAL. If this flag
is not set the kernel dosen't update the cached rssi value to upper layer.
To mitigate this issue, set the "sinfo->filled" when returning the
cached value to the upper layer during roaming.
