wifi: cfg80211: fully move wiphy work to unbound workqueue
[ Upstream commit e296c95eac655008d5a709b8cf54d0018da1c916 ]
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.
