migration: fix implicit integer division in migration_update_counters

Browse Source 
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.
