qcacld-3.0: Fix get sap connected sta info fcs counter always 0

Stats event from target might have several sub events, and some event
has no peer stats but have adv/ext2 peer stats.

Check ext/ext2 peer stats even no peer stats in
target_if_cp_stats_extract_peer_stats(). Fix copy adv stats size error
in tgt_mc_cp_stats_prepare_n_send_raw_station_stats(). Although
get_station_stats_cb and get_peer_stats_cb is union callbacks,
better to assign to get_station_stats_cb because it is for
TYPE_STATION_STATS.
