patch to set correctly the 802.11n Ness parameter value

I observed that the Ness parameter is set equal to the number of TX antenna, i.e. it is set to 1 as the current implementation is limited to 1x1 802.11n systems. 

Nevertheless, for such systems which does not use several streams nor beamforming, the Ness parameter should be always equal to 0.

In attachment, I provide a patch to correct the issue.
