[S390] dasd: fix bug in dasd initialization cleanup
The initialization of the dasd_eer code is one of the last steps of the dasd driver initialization. When initialization fails in one of the earlier steps, the dasd_exit function is called to clean up what has been done so far. So the dasd_eer_exit function may be called, although the dasd_eer_init function wasn't called before and dasd_eer_exit tries to unregister a misc device that wasn't registered, which results in a BUG. Make sure that dasd_eer_exit can be called without initialization. Use a dynamically allocated struct miscdevice instead of a static one, so we only try to unregister the device if it exists and was actually registered.
