spdk_io_device_register() doesn't have a return value, but we can at
least catch trivial mistakes like neglecting to pass a valid io_device
or create/delete callback in debug builds.
One invalid unit test case that passed NULL for all parameters is
removed, since there's no way to make that work without adding a return
value instead of asserts.
