qcacld-3.0: Let non-DBS chips pass STA+STA concurrency check during reassoc

During reassociation, cm_check_for_reassoc_hw_mode_change() is called
to check the coming concurrency is supported or not after preauth is
done. For non-DBS chip, due to STA+STA concurrency is not supported
by FW, the connection manager will run into state disconnecting from
roaming and disconnect current connection by sending disassociate frame,
then do new connection again. It's not normal roaming flow in which
disassociate frame should not be seen over the air.

Per the reassociation flow, it will internally delete previous connection
first, so can call policy_mgr_store_and_del_conn_info_by_vdev_id first to
make sure concurrency checking can pass even if a new STA connection is
coming up.
