Actually forget this patch. We can just make scsi-ml handle this.

sd does not allow scsi_io_completion to retry commands for
SG_IO requests, and it make sense that it should not happen for st
SG_IO commands too. This patch returns to the block layer that
the whole command completed and relies on the caller to check
the request errors field.
Patch was made against scsi-rc-fixes.
