Revert "MINOR: quic: Useless TX buffer size reduction in closing state"

By chasing a QUIC regression on 3.0, we found this commit. We don't if it
introduced a regression or not but the context is quite different. So let's
revert it for now, especially because it is not a bug fix, to review it
later.

This reverts commit 6edc24a81f9347d49f674c9fdd6641e922b85132.
