dlm: init per node debugfs before add to node hash

Avoiding potential issues when a node is added to the hash but the
debugfs is not NULL or IS_ERR() so a potential iteration over the hash
and debugfs_remove() will not fail like in dlm_midcomms_exit().

However dlm_midcomms_exit() will be called in module init/exit function
and the hash should be empty anyway at those stages. We change the
behavior as cleanup to avoid potential issues.
