[PATCH AUTOSEL 6.1 01/15] wifi: cfg80211: remove links only on AP

[Sasha Levin]

From: Johannes Berg <johannes.berg@xxxxxxxxx>

[ Upstream commit 34d4e3eb67fed9c19719bedb748e5a8b6ccc97a5 ]

Since links are only controlled by userspace via cfg80211
in AP mode, also only remove them from the driver in that
case.
