wifi: mac80211: Fix setting vif links

[ Upstream commit e7182c4e6bbeafa272612e6c06fa92b42ad107ad ]

When setting the interface links, ignore the change iff both the
valid links and the dormant links did not change. This is needed
to support cases where the valid links didn't change but the dormant
links did.
