BUG/MEDIUM: stream: Don't use small buffer on queuing with a request data filter

Browse source 
When there is a filter registered on the request data forwarding, we must
disable usage of the small buffers. For now it is safer to do so because we
don't know if the filter will properly handle the small buffers. In
addition, there is a true issue because it is possible to never re-arm the
receives in that case because the buffer reserve must be respected. This
leads to think a small buffer is always full, even empty one.

No backport needed.
