This allows user-space (wpa_supplicant) to disable
short guard interval (SGI) for 20Mhz.  The SGI-40
disable option is already handled.

And you tested this? And it actually did something, despite
mac80211_ht_capa_mod_mask not including it??

It was busted...new patch sent, and the new one was freshly tested and
appears to work as desired.

Thanks,
