[ Upstream commit c71c4e49afe173823a2a85b0cabc9b3f1176ffa2 ]
Fix the logic that sets the enable/disable flag for the source MAC filter according to firmware spec 1.7.1.
In the original firmware spec. before 1.7.1, the VF spoof check flags were not latched after making the HWRM_FUNC_CFG call, so there was a need to keep the func_flags so that subsequent calls would perserve the VF spoof check setting. A change was made in the 1.7.1 spec so that the flags became latched. So we now set or clear the anti- spoof setting directly without retrieving the old settings in the stored vf->func_flags which are no longer valid. We also remove the unneeded vf->func_flags.
