xen: fixes for 4.20-rc5

It contains the following fixes:
- A revert of a previous commit as it is no longer necessary and has
  shown to cause problems in some memory hotplug cases.
- Some small fixes and a minor cleanup.
- A patch for adding better diagnostic data in a very rare failure case.

Thanks.

Juergen
