Hugo Benichi 9cd15c7f2e Nat464Xlat: internal state guards cleanup + state enum
This patch does some cleanup of Nat464Xlat internal state guards
against the Nat464Xlat state Idle | Started | Running, which reduces
code nesting.

It also replaces introspection of internal state for distinguishing
between different stages in 464xlat lifecycle with an enum explicitly
introducing these three Idle | Started | Running states.
