That's probably a file ID.  The "extra_info" field of an
"smb_saved_info_t" structure is usually a pointer to a
SMB-message-type-specific data structure, but sometimes it's used to
hold a numerical file ID instead.

It looks as if a file ID was put there, but the code is assuming that
it's not a file ID.
