net: fix address check in rtnl_fdb_del
Commit 6681712d67eef14c4ce793561c3231659153a320
vxlan: generalize forwarding tables
relaxed the address checks in rtnl_fdb_del() to use is_zero_ether_addr().
This allows users to add multicast addresses using the fdb API. However,
the check in rtnl_fdb_del() still uses a more strict
is_valid_ether_addr() which rejects multicast addresses. Thus it
is possible to add an fdb that can not be later removed.
Relax the check in rtnl_fdb_del() as well.
