Subject: [PATCH iproute2-next 02/20] bridge: vni: Remove dead code in group argument parsing

is_addrtype_inet_not_multi(&daddr) may read an uninitialized "daddr". Even
if that is fixed, the error message that follows cannot be reached because
the situation would be caught by the previous test (group_present).
Therefore, remove this test on daddr.

Fixes: 45cd32f9f7d5 ("bridge: vxlan device vnifilter support")
