Thanks for your suggestion. I'd be lucky if this was true. But the most important users of scsi_result_to_blk_status() are in scsi_lib.c (scsi_io_completion_action(), scsi_io_completion_nz_result()). If I move scsi_result_to_blk_status() to vmlinux without exporting it, it won't be available in the SCSI core any more, at least not with CONFIG_SCSI=m.
