Subject: [PATCH] glx: Set ContextTag for all contexts

Currently, xorgGlxMakeCurrent() would set the context tag only for
indirect GLX contexts.

However, several other places expect to find a context for the tag or
they would raise a GLXBadContextTag error, such as WaitGL() or WaitX().

Set the context tag for direct contexts as well, to avoid raising an
error and possibly killing the client.

Thanks to Erik Kurzinger <ekurzinger@nvidia.com> for spotting the issue.
