Tests: avoid premature stream reset in h3_limit_req.t.
STREAM and RESET_STREAM frames could be batched, which prevents the stream
from being processed and changes the status code. The fix is to wait for
the stream acknowledgment. Here we just look at the largest acknowledged,
this should be enough for simple cases.
