[DLM] fix add_requestqueue checking nodes list
Requests that arrive after recovery has started are saved in the requestqueue and processed after recovery is done. Some of these requests are purged during recovery if they are from nodes that have been removed. We move the purging of the requests (dlm_purge_requestqueue) to later in the recovery sequence which allows the routine saving requests (dlm_add_requestqueue) to avoid filtering out requests by nodeid since the same will be done by the purge. The current code has add_requestqueue filtering by nodeid but doesn't hold any locks when accessing the list of current nodes. This also means that we need to call the purge routine when the lockspace is being shut down since the add routine will not be rejecting requests itself any more.
