xen: fixes for 4.19-rc2

It contains:
- minor cleanup avoiding a warning when building with new gcc
- a patch to add a new sysfs node for Xen frontend/backend drivers
  to make it easier to obtain the state of a pv device
- two fixes for 32-bit pv-guests to avoid intermediate L1TF vulnerable
  PTEs

Thanks.

Juergen
