Don't WARN about expected W+X pages on Xen

Currently Xen PV domains (or at least dom0) on amd64 tend to have a
large number of low kernel pages with W+X permissions.  It's not
obvious how to fix this, and we're not going to get any new
information by WARNing about this, but we do still want to hear about
other W+X cases.  So add a condition to the WARN_ON.
