Some cleanups+optimizations primarily around offline_and_remove_memory().
Patch #1 drops the "unsafe unplug" feature where we might get stuck in
offline_and_remove_memory() forever.
Patch #2 handles unexpected errors from offline_and_remove_memory() a bit
nicer.
Patch #3 handles the case where offline_and_remove_memory() failed and
we want to retry later to remove a completely unplugged Linux memory
block, to not have them waste memory forever.
Patch #4 something I had lying around for longer, which reacts faster
on config changes when unplugging memory.

This looks like something that's reasonable to put in this linux, right?
These are fixes even though they are for theoretical issues.
Yes, but these are not high-priority fixes+optimizations. So if you feel
like we should be delaying them, fine with me.
On the other hand, getting them in now also shouldn't really hurt.
Especially patch #1 might be better of just going in soner than later.
