[RFA 3/6] Comment out some unused overlay code

[Tom Tromey <tom@tromey.com>]

This patch comments out some unneeded initializations in overlay code
in symfile.c.  Normally I would not comment out code like this, but
the uses of "size" in these functions are commented out.  If you'd
prefer I could just delete the comments.

2016-06-06  Tom Tromey  <tom@tromey.com>

	* symfile.c (simple_overlay_update_1): Comment out initialization
	of "size".
	(simple_overlay_update): Likewise.
