[PATCH] fix cdrom autoclose

The attached patch fixes the CD-ROM autoclose.  It is broken in recent
kernels for CD-ROMs that do not properly report that the tray is opened.
Now on such a drives the kernel will do one close attempt and check for the
disc again.  This is how it used to work in the past.
