dlm: fix rcom_names message to self
The recent patch to validate data lengths in rcom_names messages failed to account for fake messages a node directs to itself before ever sending it. In this case we need to fill in the message length in the header for the validation code to use. Signed-off-by: David Teigland <teigland@redhat.com>
