net: flow: Add l3mdev flow update
Add l3mdev hook to set FLOWI_FLAG_SKIP_NH_OIF flag and update oif/iif in flow struct if its oif or iif points to a device enslaved to an L3 Master device. Only 1 needs to be converted to match the l3mdev FIB rule. This moves the flow adjustment for l3mdev to a single point catching all lookups. It is redundant for existing hooks (those are removed in later patches) but is needed for missed lookups such as PMTU updates.
