[RFC][PATCH 29/34] x86/xen: Remove extra get_cpu_address_sizes() call

Xen PV should now be avoiding reading 'x86_config' at all due to
previous fixes. Even if something was missed, it should now get sane
values *and* be able to survive long enough to get a warning out later
in boot.

Remove the belt-and-suspenders call to get_cpu_address_sizes().
