dlm: remove dlm_send_rcom_lookup_dump
This function was only for debugging. It would be called in a condition that should not happen, and should probably have been removed from the final version of the original commit. Remove it because it does mutex lock under spin lock. Signed-off-by: David Teigland <teigland@redhat.com>
