nl80211: rework locking
When I added scanning to cfg80211, we got a lock dependency like this:
rtnl --> cfg80211_mtx
nl80211, on the other hand, has the reverse lock dependency:
cfg80211_mtx --> rtnl
which clearly is a bad idea. This patch reworks nl80211 to take these
two locks in the other order to fix the possible, and easily
triggerable, deadlock.
