[ROSE]: Fix routing table locking in rose_remove_neigh.
The locking rule for rose_remove_neigh() are that the caller needs to hold rose_neigh_list_lock, so we better don't take it yet again in rose_neigh_list_lock. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S. Miller <davem@davemloft.net>
