Do not queue zero sized segments.
Commit 16b751b6c610ec2c5a913cb8a818e9239ee7da71 introduced a bug where writes of
zero size would end up queueing a zero sized segment which will cause the
sandbox to panic when trying to send a zero sized segment(e.g. after an RTO) as
netstack asserts that the all non FIN segments have size > 0.
This change adds the check for a zero sized payload back to avoid queueing
such segments. The associated test panics without the fix and passes with it.
