MFC r314307: Add support for SIMs without autosense.
If we asked to send sense data by setting CAM_SEND_SENSE, but SIM didn't
confirm transmission by setting CAM_SENT_SENSE, assume it was not sent.
Queue the I/O back to CTL for later REQUEST SENSE with ctl_queue_sense().
This is needed for error reporting on SPI HBAs like ahc(4)/ahd(4).
