mac80211: fix various components for the new 5 and 10 MHz widths
This is a collection of minor fixes:
* don't allow HT IEs in IBSS for 5/10 MHz
* don't allow HT IEs in Mesh for 5/10 MHz
* don't downgrade from/to 5 and 10 MHz channels
* don't try HT rates for 5 and 10 MHz channels when selecting rates
