PROTON-925: old line of code was initializing remote_channel_max to zero.
> proton-c seems to treat unspecified channel-max as implying 0
> -------------------------------------------------------------
>
> Key: PROTON-925
> URL: https://issues.apache.org/jira/browse/PROTON-925
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: 0.10
> Reporter: Gordon Sim
> Assignee: michael goulish
> Priority: Blocker
> Fix For: 0.10
>
>
> If max-channels is not specified in the open, it appears the latest proton-c
> treats that as implying the maximum is 0 though the spec states the default
> is 65535.
> This breaks compatibility with previous proton releases. E.g. the following
> is the interaction between a sender using the latest 0.10 and a receiver
> using proton 0.9.
