[PATCH RESEND 4/5] mac80211: update ht flag if bss configuration changed

[Emmanuel Grumbach <egrumbach@gmail.com>]

From: Avri Altman <avri.altman@intel.com>

The bug concerned failing to update the ht flag properly.
updating the ht flag when bss configuration changes should
be done independently of channel changes.
