It looks like the driver sent a reset to the device on its own without
reporting it to the mid-layer.
There's an expecting_cc_ua flag in the scsi_device. It gets set on
error recovery actions, or if the device does something to detect or
trigger a reset (that's the scsi_report_device_reset() and
scsi_report_bus_reset() API's).
