Bjoern A. Zeeb b70179a932 LinuxKPI: 802.11: correct HT protection fields 
It seems during the initial buildup of the file, the defines were
either mixed or not flagged as "FIXME".
Define the values through to the net80211 definitions and also
annotate them by at least some standards reference.

Fixes:		6b4cac814e

Differential Revision: https://reviews.freebsd.org/D43658
