qcacld-3.0: use sync method in SAP delete peers

when CSA happens, peer delete will not call
SAP de-register flow, of which may lead adapter
sta_info struct dirty. When STA interface is assigned
new peer_id, it has possibility to conflict with
dirty sta_id in adapter sta_info list. So change to
sync peer delete and notify umac to clean sta_info.
