[PATCH 3/7] xen: Take into account new frame table address since Xen 4.3

[Daniel Kiper <daniel.kiper-QHcLZuEGTsvQT0dZR+AlfA@public.gmane.org>]

Since Xen commit a8d2b06db7826063df9d04be9d6f928bf2189bd0
(x86: extend frame table virtual space) frame table has
new address. Take into account that thing.
