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
