BUG/MEDIUM: mux-h1: make sure we always have at least one HTX block to send

Commit 84cca66 ("BUG/MEDIUM: htx: When performing zero-copy, start from
the right offset.") uncovered another issue which is that the send function
may occasionally be called without any block. It's important to check for
this case when computing the zero-copy offsets.

No backport is needed.
