cdrom: move shared static to cdrom_device_info
The keeplocked variable in the cdrom driver is shared across multiple
drives, but set in per-device ioctls. Move it to the per-device struct,
avoiding that the setting on one drive affects the driver's behavior
when closing another.
[ Impact: limit udev's confusion to one drive when a CD burning program
unlocks the CD door at the end of burning. ]
