ipvlan: avoid spinlock contention in ipvlan_multicast_enqueue()
Under high stress, we spend a lot of time cloning skbs,
then acquiring a spinlock, then freeing the clone because
the queue is full.
Add a shortcut to avoid these costs under pressure, as we did
in macvlan with commit 0d5dc1d7aad1 ("macvlan: avoid spinlock
contention in macvlan_broadcast_enqueue()")
