nfp: flower: fix pedit set actions for multiple partial masks
Previously we did not correctly change headers when using multiple
pedit actions with partial masks. We now take this into account and
no longer just commit the last pedit action.
Fixes: c0b1bd9a8b8a ("nfp: add set ipv4 header action flower offload")
