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.
