Gertjan van Wingerde d24deb2580 mac80211: Add define for TX headroom reserved by mac80211 itself. 
Add a definition of the amount of TX headroom reserved by mac80211 itself
for its own purposes. Also add BUILD_BUG_ON to validate the value.
This define can then be used by drivers to request additional TX headroom
in the most efficient manner.
