Fix buffer leak from L2 flooding replication process
vlib_buffer_free_inline actually checks (b->flags & VLIB_BUFFER_RECYCLE) in order to decide whether to free the packet or not. Although the flag was correctly set in replication_prep, it is not removed by replication_recycle during last iteration. This patch just removes VLIB_BUFFER_RECYCLE when is_last is set.
