With static RPC slots, the xprt backlog queue stats were useful in showing when the transport (TCP) was starved by lack of RPC slots. The new dynamic RPC slot code, commit d9ba131d8f58c0d2ff5029e7002ab43f913b36f9, always provides an RPC slot and so only uses the xprt backlog queue when the tcp_max_slot_table_entries value has been hit or when an allocation error occurs. All requests are now placed on the xprt sending or pending queue which need to be monitored for debugging. The max_slot stat shows the maximum number of dynamic RPC slots reached which is useful when debugging performance issues. Add the new fields at the end of the mountstats xprt stanza so that mountstats outputs the previous correct values and ignores the new fields. Bump NFS_IOSTATS_VERS.
