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.
