Adrian Chadd 363846a7e3 net80211: fix VHT80/VHT160 transmit width checks 
I didn't double check to see if ni_chw had been updated to actually
implement values other than 20/40.  It's just implementing the
HT channel width stuff during both association and upon receiving
a HT TX channel width action frame.

This meant the VHT80/VHT160 transmit width checks were never
going to be true, as ni_chw is never set to VHT80 / VHT160.

After checking the HT action frame and looking for VHT changes,
I'm pretty sure there's nothing explicit about VHT width, as it's
normally done via CCA (clear channel access) and/or RTS/CTS exchanges -
each 20MHz subchannel is RTS/CTS'ed / will be checked and if they're
busy, a narrower frame will be transmitted.

So, change the VHT80 / VHT160 checks to only check if ni_chw is 20MHz.
If it's 20MHz then a HT action frame has come out saying to TX at 20MHz,
and we should obey it.  Otherwise, do 80/160MHz as available.
