Memory leak occurs when ldlm_lock_new fails in ldlm_lock_create.
The flow is below.

ldlm_lock_create
 res = ldlm_resouce_new
  atomic_set(&res->lr_refcount, 1);
 ldlm_lock_new //if failed
   RETURN(ERR_PTR(-ENOMEM)); // ldlm_resource_putref should be executed

res->lr_refcount remains and the node can not be umount.
