cifs: print session id while listing open files

commit 175b54abc443b6965e9379b71ec05f7c73c192e9 upstream.

In the output of /proc/fs/cifs/open_files, we only print
the tree id for the tcon of each open file. It becomes
difficult to know which tcon these files belong to with
just the tree id.

This change dumps ses id in addition to all other data today.
