Illegal handles in FindClose

[Dominik Strasser]

The application I am trying to make runnable passes an illegal handle to
FindClose. It is 0xcccccccc which is an unitialized stack address (at
least I remember to have seen those when I was doing Windoze programs).
I wrapped the access into an exception handler.

ChangeLog:
	* files/dos_fs.c
	Dominik Strasser <dominik.strasser at mchp.siemens.de>
	Allow illegal handles in FindClose
