firmware: provide stubs for the FW_LOADER=n case
libsas has a case where it uses the firmware loader to provide services, but doesn't want to select it all the time. This currently causes a compile failure in libsas if FW_LOADER=n. Fix this by providing error stubs for the firmware loader API in the FW_LOADER=n case.
