[Libvir] [PATCH] pae/nonpae capabilities for paravirt xen guests

[David Lutterkort <dlutter redhat com>]

I noticed that the guest capabilities on a xen dom0 always contain both
the pae and nonpae feature - AFAIK, you can't mix pae/nonpae guests and
hosts, and only one of the features should be there.

The attached patch contains the obvious fix.
