When an error occurs on the device, an interrupt is reported.
When the firmware forwards the interrupt to the driver and masks the
error. If the driver does not enable error reporting when an error does
not need to be reset, the device does not report the error to the driver
when the error occurs again. Therefore, after the driver obtains the
information, the error reporting needs to be enabled again.

The error detection of the data aggregation feature is separated from
the compression/decompression feature. This patch enables the error
detection and reporting of the data aggregation feature. When an
unrecoverable error occurs in the algorithm core, the device reports
the error to the driver, and the driver will reset the device.
