I actually would expect it to happen for UC QPs, since the code path
is exactly the same. For UD QPs, the WQE format is slightly
different, which explains the difference.

You're right that there's something fishy. It turns out our
calculation of the possible WQE size adds together several worst cases
that can't all happen at once. I'll look at how to clean this up.
