xen p2m: annotate variable which appears unused

CC      arch/x86/xen/p2m.o
arch/x86/xen/p2m.c: In function 'm2p_remove_override':
arch/x86/xen/p2m.c:460: warning: 'address' may be used uninitialized in this function
arch/x86/xen/p2m.c: In function 'm2p_add_override':
arch/x86/xen/p2m.c:426: warning: 'address' may be used uninitialized in this function

In actual fact address is inialised in one "if (!PageHighMem(page))"
statement and used in a second and so is always initialised before
use.
