The verbose flag was added in commit 81c7288b170a ("sched: cls: enable verbose logging") to avoid suppressing logging of error messages that occur "when the rule is not to be exclusively executed by the hardware". However, such error messages are currently suppressed when setup of flow action fails. Take the verbose flag into account to avoid suppressing error messages. This is done by using the extack pointer initialized by tc_cls_common_offload_init(), which performs the necessary checks.
