iwd: Never lock to BSSID in complete_connection

The AP BSSIDs created by the iwd backend are made up so never lock the
connections to them.  It probably wouldn't matter as long as the iwd
backend is used but the fake BSSID could stay in the connection
properties even if the user switches to wpa_supplicant.
