Currently, link frequency is fetched from roam sync indication
based on vdev_id. But the vdev_id is of assoc link in OWE/1x
cases(where link vdev would be down as part of roam sync handling)
but it would of non-assoc link in case of other modes
like SAE/WPA2/.. So current fetching of frequency based vdev_id
may give invalid frequency in SAE case as non-assoc link vdev_id
is passed.
Fetch the frequency based on link mac addr to avoid such failures.
