Remove obsolete checks for ldisc_send with len == 0.

Browse Source 
This reverts commit 4634cd47f7 and
commit 43a63019f5, both of which
introduced checks at ldisc_send call sites to avoid triggering the
assertion that len != 0 inside ldisc_send. Now that assertion is gone,
it's OK to call ldisc_send without checking the buffer size.
