target: go through normal processing for zero-length REQUEST_SENSE
Now that spc_emulate_request_sense has been taught to process zero-length REQUEST SENSE correctly, drop the special handling of unit attention conditions from transport_generic_new_cmd. However, for now REQUEST SENSE will be the only command that goes through emulation for zero lengths.
