commit a3d0562d4dc039bca39445e1cddde7951662e17d upstream.

This reverts commit 7073ea8799a8cf73db60270986f14e4aae20fa80.

We must not try to connect the socket while the transport is under
construction, because the mechanisms to safely tear it down are not in
place. As the code stands, we end up leaking the sockets on a connection
error.
