The module namespace support has been introduced to allow restricting
exports to specific modules only, and intended for in-tree modules such
as kvm. Make this intention explicit by disallowing out of tree modules
both for the module loader and modpost.

In my understanding, an external module with the same name
can override the internal one.

This change disallows such a use-case.

Hmm I'm not familiar with this, but for such cases to be legitimate we can
assume the external module has to be derived from the internal one and not
something completely unrelated impersonating the internal one? So in that
case just patch 2 alone would be sufficient and not break any legitimate use
cases?
