In the scenario about MLO 5 GHz + 6 GHz and 6 GHz is non-tx AP in
MBSSID, if DUT tries to connect 5 GHz link as assoc link and uses
the scan entry generated from 5 GHz beacon. Then there is no info
about profile index and count in the scan entry and these info is
necessary for firmware when vdev up.
To resolve this issue, get the info from 6 GHz scan entry if it
exists.
