int31 get descriptor should return correct segment limit

[David Hammerton <david@transgaming.com>]

This was diff'd from winex cvs, but it should apply fine to winehq cvs (after 
looking briefly at cvs.winehq.com). Fixes a crash in an old win16 game.

Changelog:
   * 'get descriptor' in the int31 handler should return the correct segment 
limit to the program.
