[S390] Remove BUILD_BUG_ON() in vmem code.
Remove BUILD_BUG_ON() in vmem code since it causes build failures if the size of struct page increases. Instead calculate at compile time the address of the highest physical address that can be added to the 1:1 mapping. This supposed to fix a build failure with the page owner tracking leak detector patches as reported by akpm. page-owner-tracking-leak-detector-broken-on-s390.patch can be removed from -mm again when this is merged.
