> Add missing validation of tc and queue id values sent by a VF in
> ice_vc_cfg_q_bw().
> Additionally fixed logged value in the warning message, where max_tx_rate was
> incorrectly referenced instead of min_tx_rate.
> Also correct error handling in this function by properly exiting when invalid
> configuration is detected.
