SVN rev 222498 on 2011-05-30 15:06:57Z by adrian
Enable setting the short-GI bit when TX'ing HT rates but only if the
hardware supports it.
Since ni->ni_htcap in hostap mode is what the remote end has advertised,
not what has been negotiated/decided, we need to check ourselves what
the current channel width is and what the hardware supports before
enabling short-GI.
It's important that short-GI isn't enabled when it isn't negotiated
and when the hardware doesn't support it (ie, short-gi for 20mhz channels
on any chip < AR9287.)
I've quickly verified this on the AR9285 in 11n mode.
