802.11: clean up/fix HT support
This patch cleans up a number of things:
* the unusable definition of the HT capabilities/HT information
information elements
* variable names that are hard to understand
* mac80211: move ieee80211_handle_ht to ht.c and remove the unused
enable_ht parameter
* mac80211: fix bug with MCS rate 32 in ieee80211_handle_ht
* mac80211: fix bug with casting the result of ieee80211_bss_get_ie
to an information element _contents_ rather than the
whole element, add size checking (another out-of-bounds
access bug fixed!)
* mac80211: remove some unused return values in favour of BUG_ON
checking
* a few minor other things
