wifi: mt76: assign link_id when sending probe request during scan

Browse Source 
The link_id in info->control.flags is required by mt7996 to select the
correct mt76_wcid for transmission.

Not assigning the link_id in info->control.flags is equivalent to
assigning the link_id to 0, causing mt7996 to select link_id 0 for
transmission, so probe requests sent on behalf of an MLD vif scanning
via a different link were transmitted with the wrong per-link wcid.
