[PATCH 0/4] MR7287: ntdll: Avoid using current_modref.

[Jacek Caban (＠jacek)]

This is a cleanup in preparation for !7. Originally, !7 extended the use of `current_modref`, but I think we could avoid that with a more direct approach. Most of these changes are no-ops.

For the relay handler, we no longer treat `GetProcAddress` calls inside `DllMain` as coming from a loaded DLL. I believe this was more of a side effect of how the code was structured rather than an intentional behavior that needs to be preserved.

One more use of `current_modref` remains, which will be removed by !7.
