[ Upstream commit 166b6a46b78bf8b9559a6620c3032f9fe492e082 ]
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.
