net/ixgbe/base: allow setting MAC anti spoofing per VF

Browse Source 
Make ixgbe_set_mac_anti_spoofing() consistent with the other
functions that deal with setting VLAN and Ethertype spoofing by
changing the prototype to accept a VF parameter.

Also change the logic for writing the PFVFSPOOF register to be similar
to the MAC and Ethertype functions.
