mac80211: resume properly, add suspend/resume test
When mac80211 resumes, it currently doesn't reconfigure the interfaces
entirely and also doesn't reconfigure BSS information -- fix this.
Also, to be able to test this, add a debugfs file that just calls
the suspend/resume code to see what happens when we go through that,
without needing the time-consuming suspend/resume cycle.
(Original version broke the build for CONFIG_PM=n. Define alternative
functions for that situation. -- JWL)
