[PATCH 6.7 161/713] wifi: mac80211: use deflink and fix typo in link ID check

[Sasha Levin]

From: Benjamin Berg <benjamin.berg@xxxxxxxxx>

[ Upstream commit e10322810ce0d0d4a5a319458c4e1e052c6fe9be ]

This does not change anything effectively, but it is closer to what the
code is trying to achieve here. i.e. select the link data if it is an
MLD and fall back to using the deflink otherwise.
