A-ha! This is what I was looking for in 1/2. Okay, but I'd rather note
this fact in 1/2 commit message to make it more obvious.

So previously, calling virDomainSetMaxMemory() on an inactive LXC domain
would succeed. Now, after the change, due to problem with _CURRENT,
_LIVE and _CONFIG this will basically return success, but without any
effect on the domain config. And that's wrong.

Moreover, I think these two patches can be joined into one.
