mapping in [`WindowsSocketError`](https://github.com/apache/mesos/blob/1600ebc6901239ae86e4e133c82d3424c56c978e/3rdparty/stout/include/stout/windows/error.hpp#L124)
(the underlying type of `SocketError` on Windows) so you can manually construct it with `ENOTCONN`
and its mapped to `WSAENOTCONN` on Windows. Thing is, then we'd also need to make sure comparisons
are done the same way. Hm...

A simpler approach may just be the latter half of that suggestion. If you compare `WindowsSocketError`
to `ENOTCONN`, have the comparator return `true` if its type is either `ENOTCONN` (for a hard-code
like this) or `WSAENOTCONN` (from an actual OS error).

Otherwise, I'd also suggest not returning `ENOTCONN` at all, since this code is being a bit
misleading about the state of the error. That is, I think it's expected that `ENOTCONN` is
only returned when an OS socket function actually errors with `ENOTCONN`, and this error logic
is our own case of having never initialized. We could return our own error instead, that's
the same on both Linux and Windows (and BSD etc.).
