Subject: [PATCH] Do not emit "unexpected" message on shutdown

During shutdown, net_kernel process that is linked to an
acceptor, gracefully terminates, triggering
`{EXIT, net_kernel, shutdown}` message sent to the acceptor.

However acceptor does not expect it, and instead of a graceful
shutdown logs a confusing warning.
