BUG/MAJOR: connections: Close the connection before freeing it.

Browse Source 
In si_release_endpoint(), if the end point is a connection, because we don't
know which mux to use it, make sure we close the connection before freeing it,
or else, we'd have a fd left for polling, which would point to a now free'd
connection.

This should be backported to 1.9.
