stream, vconn: Fix comments.

All streams and all vconns are "active", so there's no point in noting that
requirement in comments.  (A long time ago, active and passive vconns were
conflated instead of having passive vconns broken out as pvconns.  But
active and passive streams have always been distinct.)
