MEDIUM: connection: make conn_sock_shutw() aware of lingering

Instead of having to manually handle lingering outside, let's make
conn_sock_shutw() check for it before calling shutdown(). We simply
don't want to emit the FIN if we're going to reset the connection
due to lingering. It's particularly important for silent-drop where
it's absolutely mandatory that no packet leaves the machine.
