`downtime * 10 < postcopy_time` was an unnormalized wall-clock
heuristic (commit e80a4150a5) that fails on fast hosts, where the
bitmap payload now transfers in under a second.
Check the actual invariant instead: right after RESUME, bitmap0's
content hash on the destination must not yet match the fully
migrated value. Throttle max-bandwidth first, since all-zero chunks
skip the payload write and would otherwise let a fast host finish
the transfer before the check runs.
