svn commit: r211301 - head/sys/netinet6

New Revision: 211301

Log:
  In rip6_input(), in case of multicast, we might skip the normal processing
  and go to the next iteration early if multicast filtering would decide that
  this socket shall not receive the data.
  Unlock the pcb in that case or we leak the read lock and next time trying
  to get a write lock, would hang forever.
