    migration: fix implicit integer division in migration_update_counters

    switchover_bw is a uint64_t, so switchover_bw / 1000 results in an
    integer division. This value is then assigned to expected_bw_per_ms
    which is of type double. This results in losing precision and is type
    unsafe. Adding explicit cast ensures floating-point division.
