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.
