Subject: [PATCH xserver 27/27] 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 and set currentClient.

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