The BUG_ON added to the multicast code in commit 7f220ed1f063 ("batman-adv:
Fix potential synchronization issues in mcast tvlv handler") will crash the
kernel when the statement is true. This is not strictly required and a
WARN_ON is enough to raise attention.

Sounds good, that'll probably spare us some discussions about
BUG_ON()s on netdev :).
