Wenkai Lin a3bece3678 uacce: fix cdev handling in the cleanup path 
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.

Fixes: 015d239ac0 ("uacce: add uacce driver")
