qcacld-3.0: Allow hw mode change for dbs 2x2 target

Previously, the hw mode changing is not allowed when SAP is CAC
state in old target which supports 1x1 dbs. The reason is
some action frame would be sent out when chainmask changes in
those target. But for 2x2 dbs target, chainmask is not changed
and hence not action frame will be sent out.
Allow the hw mode change for 2x2 dbs target when SAP is CAC.
