[patch] fix cdrom autoclose

Hi Andrew.

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.

Can this please be applied?
