We should not be allowing a timeout to reset when a drain is in progress on
it (either async or sync drain).

At this moment the only user of drain is TCP, but TCP wouldn't reschedule a
callout after it has drained it, since it drains only when a tcpcb is closed.
This for now the problem isn't observed.
