net/sched: cls_api: Fix flow action initialization

2022-07-20T09:54:27+00:00

The cited commit refactored the flow action initialization sequence to
use an interface method when translating tc action instances to flow
offload objects. The refactored version skips the initialization of the
generic flow action attributes for tc actions, such as pedit, that allocate
more than one offload entry. This can cause potential issues for drivers
mapping flow action ids.

Populate the generic flow action fields for all the flow action entries.
