[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. Signed-off-by: Steve French <smfrench@gmail.com>
