To support act stats, provide the action instance
in flow offload operation. This instance will be
saved by drivers, and used to directly update the
stats on.

v1->v2
- talked to Paul and he explained that this patch is to provide
interface for OFED and is an alternative to bring lots and lots
of upstream patches. This isn't used by upstream driver and so is
unused also in bluefield kernel.
External modules such as OFED can use it.
