HT rate set in net80211 not changeable for STA

[Alexander Egorenkov]

This MCS32 HT rate causes problems with AMRR. If the connection between a
client and an AP is very good and the AP supports MCS32, the client keeps
increasing the Tx rate upto MCS32 and then the problems begin because the
client starts to send with MCS32.
