dlm: fix invalid cluster name warning

[ Upstream commit 3595c559326d0b660bb088a88e22e0ca630a0e35 ]

The warning added in commit 3b0e761ba83
  "dlm: print log message when cluster name is not set"

did not account for the fact that lockspaces created
from userland do not supply a cluster name, so bogus
warnings are printed every time a userland lockspace
is created.
