[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
