[PATCH 2/2] net/sfc: invalidate dangling MAE flow action FW resource IDs

[Ivan Malov]

When reinserting a flow (on port restart, for instance)
FW resource IDs found in the action set specification
need to be invalidated so that the new (reallocated)
FW resource IDs can be accepted by libefx again.

Fixes: 1bbd1ec2348a ("net/sfc: support action VXLAN encap in MAE backend")
