We need to return EOPNOTSUPP for the unsupported mpls action type when
setup the flow action.

In the original implement, we will return 0 for the unsupported mpls
action type, actually we do not setup it and the following actions
to the flow action entry.

Thanks!

Could I ask for a merge of net into net-next?

The patch above will be a dependency for v7 of our metering offload
patchset.
