wireless: rename ht_info to ht_operation
Since some of the HT code pre-dates 802.11n-2009 some names are wrong. The one that bothers me most is that "HT operation" is called "HT information" in our code and that causes confusion. Rename "HT information" to "HT operation" and also the control_chan field to primary_chan to match the name used in the spec.
