uacce: fix cdev handling in the cleanup path
commit a3bece3678f6c88db1f44c602b2a63e84b4040ac upstream.
When cdev_device_add fails, it internally releases the cdev memory,
and if cdev_device_del is then executed, it will cause a hang error.
To fix it, we check the return value of cdev_device_add() and clear
uacce->cdev to avoid calling cdev_device_del in the uacce_remove.
