For its concurrent requests, 046 has always filtered the offset,
probably because concurrent requests may settle in any order.  However,
it did not filter the request length, and so if requests with different
lengths settle in an unexpected order (notably the longer request before
the shorter request), the test fails (for no good reason).

Filter the length, too.

This has annoyed me for quite some time now, but when rebasing (and
testing) my FUSE export series, it became apparent that on a FUSE export
qcow2 images with -o compat=0.10 always fail this test (because the
first 56k request settles before its accompanying 8k request), so now
I'm forced to do something about it.
