HID: hidraw: improve error handling in hidraw_init()
commit bcb4a75bde3821cecb17a71d287abfd6ef9bd68d upstream.
Several improvements in error handling:
- do not report success if alloc_chrdev_region() failed
- check for error code of cdev_add()
- use unregister_chrdev_region() instead of unregister_chrdev()
if class_create() failed
