[PATCH 5.15 205/206] wifi: cfg80211: fully move wiphy work to unbound workqueue

From: Johannes Berg <johannes.berg@intel.com>

commit e296c95eac655008d5a709b8cf54d0018da1c916 upstream.

Previously I had moved the wiphy work to the unbound
system workqueue, but missed that when it restarts and
during resume it was still using the normal system
workqueue. Fix that.
