rndis_wlan: ignore OID_802_11_ADD_KEY triggered media connect indications
Setting WPA keys with OID_802_11_ADD_KEY sometimes trigger
instant media connect indication. These indications are extranous and
should be ignored, as otherwise driver would send reassociation event to
userspace which in this case is not needed.
