Don't set `writable` to true when a socket connects if the socket is
already in an ending state.
In the existing code, afterConnect always set `writable` to true. This
has been the case for a long time, but previous to commit
9b7a6914a7, the socket would still be
destroyed by `destroySoon` and emit a `'close'` event. Since that
commit removed this masking behavior, we have relied on maybeDestroy to
destroy the socket when the readble state is ended, and that won't
happen if `writable` is set to true.
If the socket has `allowHalfOpen` set to true, then `destroy` will still
not be called and `'close'` will not be emitted.
