iwlwifi: don't print module loading error if not modular
iwlwifi: don't print module loading error if not modular

If the opmode modules aren't modular, there's no point in
printing an error message that request_module() failed.
This will happen because the probe runs during iwlwifi's
init and the opmode is only added during its init.
