Small cleanups on freebsd-connect-refused patch.

Small cleanups on freebsd-connect-refused patch.

There should be no need to call be_socket_enable: that does an
event_add().  What we really want to do is event_active(), to make
sure that the writecb is executed.

Also, there was one "} if () {" that was missing an else.

I've noted that the return value for evutil_socket_connect() is
getting screwy, but since that isn't an exported function, we can fix
it whenever.
