Enable the reporting of error counters through sysfs for QAT GEN6 devices and update the ABI documentation. This enables the reporting of the following: - errors_correctable - hardware correctable errors that allow the system to recover without data loss. - errors_nonfatal: errors that can be isolated to specific in-flight requests. - errors_fatal: errors that cannot be contained to a request, requiring a Function Level Reset (FLR) upon occurrence.
