x86, srat: do not register nodes beyond e820 map

The mem= option will truncate the memory map at a specified address so
it's not possible to register nodes with memory beyond the e820 upper
bound.

unparse_node() is only called when then node had memory associated with
it, although with the mem= option it is no longer addressable.

[ Impact: fix boot hang on certain (large) systems ]
