[net-next 9/9] i40e: Remove unicast log when VF is leaving multicast mode.

[Jeff Kirsher]

From: Czeslaw Zagorski <czeslawx.zagor...@intel.com>

This patch removes unicast log when VF is leaving multicast mode.
Added check of vf->vf_states &
I40E_VF_STATE_MC_PROMISC/I40E_VF_STATE_UC_PROMISC.
Without this commit, leaving multicast mode logs "unset unicast"
in dmsg.
