Paolo Abeni says:

====================
openvswitch: remove a couple of BUG_ON()

The openvswitch kernel datapath includes some BUG_ON() statements to check
for exceptional/unexpected failures. These patches drop a couple of them,
where we can do that without introducing other side effects.

v1 -> v2:
 - avoid memory leaks on error path
