[SCSI] scsi_error: code cleanup before refactoring of scsi_send_eh_cmnd()
- regrouped variables for easier reviewing of next patch
- Support of cmnd==NULL in call to scsi_send_eh_cmnd()
- In the @sense_bytes case set transfer size to the minimum
size of sense_buffer and passed @sense_bytes. cmnd[4] is
set accordingly.
- REQUEST_SENSE is set into cmnd[0] so if @sense_bytes is
not Zero passed @cmnd should be NULL.
- Also save/restore resid of failed command.
- Adjust caller
