fsm: talloc + copy the 'id' passed into a FSM
The 'id' is used to generate the human-readable name of the FSM. However, when the FSM creates slave FSMs later, the caller-passed "ID" mgiht long be gone again (e.g. it was on stack memory). So let's copy the 'id' string to a chunk of dynamically-allocated memory at time of FSM start to ensure we have it later when creating child FSMs. Change-Id: Ib88a2c02c5c91f17b4ec1e9db57a06d6d66465fb
