I fixed these. While they seemed important to get fixed at the first
glance, I don't think the fix deserves rushing in before 4.5 got
branched off: In the _CRS case it is rather unlikely that racing
invocations would be done by an OS. And in the _BST cases the
routine has custom serialization in place already. So the fix is rather
cosmetic afaict.

I have no idea how to avoid these - we have to name the two
respective memory regions, and not us accessing every of its
fields producing warnings seems more like an overacting iasl than
a source problem to me.

These were of course trivial to address, but are also purely
cosmetic. I'll defer posting the patch until after branching too.
