igc: Add condition for qbv_config_change_errors counter
[ Upstream commit ed89b74d2dc920cb61d3094e0e97ec8775b13086 ]
Add condition to increase the qbv counter during taprio qbv
configuration only.
There might be a case when TC already been setup then user configure
the ETF/CBS qdisc and this counter will increase if no condition above.
