ipvlan: don't deref eth hdr before checking it's set
[ Upstream commit ad8192767c9f9cf97da57b9ffcea70fb100febef ]
IPvlan in L3 mode discards outbound multicast packets but performs
the check before ensuring the ether-header is set or not. This is
an error that Eric found through code browsing.
Fixes: 2ad7bf363841 (“ipvlan: Initial check-in of the IPVLAN driver.”)
