xen: regression and bug fixes for 4.0-rc1

- - Fix two regression introduced in 4.0-rc1 affecting PV/PVH guests in
certain configurations.
- - Prevent pvscsi frontends bypassing backend checks.
- - Allow privcmd hypercalls to be preempted even on kernel with
voluntary preemption. This fixes soft-lockups with long running
toolstack hypercalls (e.g., when creating/destroying large domains).

Thanks.

David
