crypto: qat - add cnv_errors debugfs file
The Compress and Verify (CnV) feature check and ensures data integrity
in the compression operation. The implementation of CnV keeps a record
of the CnV errors that have occurred since the driver was loaded.
Expose CnV error stats by providing the "cnv_errors" file under
debugfs. This includes the number of errors detected up to now and
the type of the last error. The error count is provided on a per
Acceleration Engine basis and it is reset every time the driver is loaded.
