qcacld-3.0: Disable beamformer for single chain

If there is single chain support then driver should disable
beamformer instead of enable

As part of fix, check the number of chains by intersecting the
firmware capability and ini config. If it is 1 then set
su_bformer, mu_bformer and num_soundingdim as 0
