ide/atapi scsi-disk: Make monitor eject -f, then change work 

change fails while the tray is locked by the guest.  eject -f forces
it open and removes any media.  Unfortunately, the tray closes again
instantly.  Since the lock remains as it is, there is no way to insert
another medium unless the guest voluntarily unlocks.

Fix by leaving the tray open after monitor eject.
