Filip Matusiak c8eaf3479e mac80211: Ignore VHT IE from peer with wrong rx_mcs_map
This is a workaround for VHT-enabled STAs which break the spec
and have the VHT-MCS Rx map filled in with value 3 for all eight
spacial streams, an example is AR9462 in AP mode.

As per spec, in section 22.1.1 Introduction to the VHT PHY
A VHT STA shall support at least single spactial stream VHT-MCSs
0 to 7 (transmit and receive) in all supported channel widths.

Some devices in STA mode will get firmware assert when trying to
associate, examples are QCA9377 & QCA6174.

Packet example of broken VHT Cap IE of AR9462:
