link: support RTEXT_FILTER_VF
This patch adds RTEXT_FILTER_VF mask support for SRIOV VFs. Since
SRIOV VFs don't have a defined address family (ie bridge), there
are no new address family specific operations defined.
Exposing this mask makes rtnl_link_get_num_vfs() properly return
the number of loaded SRIOV VFs.
