Fix channel try_send failure after cancel #1242

Closed erinacio closed 1 year ago

erinacio commented 1 year ago

The only case when impl.send_state_ becomes waiter seems to be that an async_receive is awaiting on an empty channel, as found in channel_service.hpp:557. As an empty channel, when no one is awaiting on it, whether send_state_ is buffer or block should solely depend on whether the channel itself is buffered or not.
