crypto: hisilicon/zip - support new error report

Browse Source 
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.
