Oh I'm all for that! It'll clean up things.

And it struck me that we can also probably (later on) add some debug code in
that function (only present when built with some debug option switched on)
that checks if the function is called multiple times before libssh2 returns,
as that would be a hint that perhaps we've done something wrong internally.
