scsi: provide general-purpose functions to manage sense data
Extract the common parts of scsi_sense_buf_to_errno, scsi_convert_sense
and scsi_target_send_command's REQUEST SENSE handling into two new
functions scsi_parse_sense_buf and scsi_build_sense_buf.
Fix a bug in scsi_target_send_command along the way; the length was
written in buf[10] rather than buf[7].
