From: Johannes Berg <johannes.b...@intel.com>
There are a few hardware flags that *are* valid to change, at least
under certain circumstances. Since drivers are doing that, add an
inline to make it easier to do correctly. They still need to take
care of locking themselves.
While at it, remove the pointless return in ieee80211_hw_set().
