smb3: print tree id in debugdata in proc to be able to help logging
When loooking at the logs for the new trace-cmd tracepoints for cifs, it would help to know which tid is for which share (UNC name) so update /proc/fs/cifs/DebugData to display the tid. Also display Maximal Access which was missing as well. Now the entry for typical entry for a tcon (in proc/fs/cifs/) looks like: 1) \\localhost\test Mounts: 1 DevInfo: 0x20 Attributes: 0x1006f PathComponentMax: 255 Status: 1 type: DISK Share Capabilities: None Aligned, Partition Aligned, Share Flags: 0x0 tid: 0xe0632a55 Optimal sector size: 0x200 Maximal Access: 0x1f01ff Signed-off-by: Steve French <smfrench@gmail.com>
