mac80211: move ieee80211_enable_ht function to mlme.c
It really belongs into that file since it is only relevant for managed mode. Move 1:1, not even whitespace changes, but make it static and remove from header file. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
