The ixgbe PF manages the default VF mac address in a separate
list from the additional VF mac filters. librte_ethdev
stores the default mac in dev->data->mac_addrs[0], however,
the ixgbevf driver re-adds mac_addr[0] when a mac filter is
removed.
ixgbevf_remove_mac_addr() is modified to avoid (re)adding
the default mac when it differs from the permanent mac.
