iwlwifi: do not set dual_stream_ant_msk for 3 streams

Browse source 
This patch fixes a bug introduced by commit "iwlwifi: adding MIMO3 support
in rate scaling". We should not set the dual_stream_ant_msk (for 2x2 MIMO)
when using a 3x3 rate, this will cause a SYSASSERT in uCode.

Note: there is no triple_stream_ant_msk, because all three antennas are used.
