Subject: Fix assert that could incorrectly be triggered when a peer closed the channel.
X-Git-Url: http://git.meshlink.io/?p=meshlink;a=commitdiff_plain;h=0f0bea383106de1a896905fdf8a56f55265bce74

Fix assert that could incorrectly be triggered when a peer closed the channel.

If we are sending AIO data on a channel and the peer closed the connection,
we could trigger an assert incorrectly.
