KVM: s390 features and fixes for 4.5 (kvm/next)

Some small cleanups
- use assignment instead of memcpy
- use %pK for kernel pointers

Changes regarding guest memory size
- Fix an off-by-one error in our guest memory interface (we might
use unnecessarily big page tables, e.g. 3 levels for a 2GB guest
instead of 2 levels)
- We now ask the machine about the max. supported guest address
  and limit accordingly.
