[PATCH]s390/char/vmur.c: memory leak Fix in the driver

["Chen, Dennis (SRDC SW)" <Dennis1.Chen@xxxxxxx>]

This patch is used to fix a memory leak issue in s390/char/vmur.c: a character device instance is 
allocated by cdev_alloc, the cdev_del will not free that space if cdev_init is applied before.
