tee: optee: fix possible memory leak in optee_register_device()
If device_register() returns error in optee_register_device(),
the name allocated by dev_set_name() need be freed. As comment
of device_register() says, it should use put_device() to give
up the reference in the error path. So fix this by calling
put_device(), then the name can be freed in kobject_cleanup(),
and optee_device is freed in optee_release_device().
Fixes: c3fa24af9244 ("tee: optee: add TEE bus device enumeration support")
