cdrom: Call cdrom_mrw_exit from cdrom_release function
Remove the cdrom_mrw_exit call from unregister_cdrom, as it invokes
block commands that can fail due to a NULL pointer dereference from the
call happening too late, during the unloading of the driver (e.g.
unplugging of USB optical drives).
Instead perform the call inside cdrom_release, thus also removing the
need for the exit function pointer inside the cdrom_device_info struct.
