When using max-bandwidth=~100Mb/s, this test fails on Travis-CI
s390x when configured with --disable-tcg:
$ make check-qtest

Per David Gilbert, "it could just be the writing is slow on s390
and the migration thread fast; in which case the autocomplete
wouldn't be needed. Perhaps we just need to reduce the bandwidth
limit."
Tuning the threshold by reducing the initial bandwidth makes the
autoconverge test pass.
