cfg80211: restrict AP beacon intervals
Multiple virtual AP interfaces can currently try
to use different beacon intervals, but that just
leads to problems since it won't actually be done
that way by drivers. Return an error in this case
to make sure it won't be done wrong.
Also, ignore attempts to change the DTIM period
or beacon interval during the lifetime of the BSS.
