PAT flags are not under control of Xen domains currently, so there is no 

point in enabling them.

Avoids:
- a warning logged by hypervisor when a domain attempts to modify the PAT
MSR.
- an error during domain resuming, where a PAT flag has been set on a page
while the hypervisor does not allow it.

ok releng@.
