xen: make sure xen_max_p2m_pfn is up to date
Keep xen_max_p2m_pfn up to date with the end of the extra memory we're adding. It is possible that it will be too high since memory may be truncated by a "mem=" option on the kernel command line, but that won't matter. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
