During an eviction, Lustre calls ldlm_namespace_cleanup,
and it will sometimes end up dumping all of the locks on a
particular resource to the console log
(ldlm_resource_complain), which is very wasteful and only
rarely helpful.

Move the debug level for this to D_NETERROR since it is in the
default debug mask.
