    Remove some unused overlay code
    
    This patch removes some unneeded initializations in overlay code in
    symfile.c.  It also deletes some old commented-out code.

    	* symfile.c (simple_overlay_update_1): Remove initialization
    	of "size", and commented-out code.
    	(simple_overlay_update): Likewise.
