wireless: T2212: bugfix for BF-ANTENNA and SOUNDING-DIMENSION flags
VHT flags deal with many variables which depend on antenna count and
supported features. BF-ANTENNA-(2|3|4) and SOUNDING-DIMENSION-(2|3|4)
were not dealt with correctly.
IEEE 802.11ac (VHT) supports at least 1 antenna and up to 8 antennas
at most. The hsotapd VHT flags may support as many but most do not.
Therefore, we need to be picky here...
