ixgbe: consolidate the configuration of spoof checking
Consolidate the logic behind configuring spoof checking:
Move the setting of the MAC, VLAN and Ethertype spoof checking into
ixgbe_ndo_set_vf_spoofchk().
Change ixgbe_set_mac_anti_spoofing() to set MAC spoofing per VF similar
to the VLAN and Ethertype functions - this allows us to call the helper
functions in ixgbe_ndo_set_vf_spoofchk() for all spoof check types and
only disable MAC spoof checking when creating MACVLAN.
