Jan Kara 42c141b6ee scsi: Fix error handling in SCSI_IOCTL_SEND_COMMAND ...

commit 84ce0f0e94 upstream.

When sg_scsi_ioctl() fails to prepare request to submit in
blk_rq_map_kern() we jump to a label where we just end up copying
(luckily zeroed-out) kernel buffer to userspace instead of reporting
error. Fix the problem by jumping to the right label.
