[spice-server v2 2/3] channel: Remove red_channel_client_disconnect_if_pending_send()

[Christophe Fergeau <cfergeau@xxxxxxxxxx>]

There is exactly one user in RedChannel, and this can be reimplemented
using already public RedChannelClient API. No need for an extra
function very specialized function with a not great name.

This commit thus removes one method from RedChannelClient public API,
and replaces it with an equivalent private helper in RedChannel.
