Subject: Disable callbacks when closing a connection.
X-Git-Url: https://git.meshlink.io/?a=commitdiff_plain;h=b4e6d4bac314221a8bdb522daef24b606f143cee;p=utcp

Disable callbacks when closing a connection.

When an application calls utcp_close() on a previously established
connection, the utcp_connection is kept around to handle FIN(ACK)
packets. However, the peer could still send some data, which should not
trigger the receive callback.
