staging: android: ion_test: fix check of platform_device_register_simple() error code

On error platform_device_register_simple() returns ERR_PTR() value,
check for NULL always fails. The change corrects the check itself and
propagates the returned error upwards.

Fixes: 81fb0b90 ("staging: android: ion_test: unregister the platform device")
