migration: notify migration state before starting thread
The migration thread runs outside the QEMU global mutex when possible.
Therefore we must notify migration state change *before* starting the
migration thread.
This allows registered listeners to act before live migration iterations
begin. Therefore they can get into a state that allows for live
migration. When the migration thread starts everything will be ready.
Without this patch there is a race condition during migration setup,
depending on whether the migration thread has already transitioned from
SETUP to ACTIVE state.
