[SMB3] Update session and share information displayed for debugging SMB2/SMB3

We were not displaying some key fields (session status and capabilities and
whether guest authenticated) for SMB2/SMB3 session in /proc/fs/cifs/DebugData.

This is needed for real world triage of problems with the (now much more
common) SMB3 mounts.
