Subject: [PATCH net-next] iavf: delete unused iavf_mac_info fields

'san_addr' and 'mac_fcoeq' members of struct iavf_mac_info are unused.
'type' is write-only. Delete all three.

The function iavf_set_mac_type that sets 'type' also checks if the PCI
vendor ID is Intel. This is unnecessary. Delete the whole function.

If in the future there's a need for the MAC type (or other PCI
ID-dependent data), I would prefer to use .driver_data in iavf_pci_tbl[]
for this purpose.
