Title: Fix a segfault that happened when a client read from the vchan

This patch was constructed more by appeal to symmetry than by understanding
the exact nature of the indices. It does stop my client from segfaulting and
actually causes it to accurately read from the vchan now though, so I have
confidence that it is correct.
