ovl: setattr: check permissions before copy-up

commit cf9a6784f7c1b5ee2b9159a1246e327c331c5697 upstream.

Without this copy-up of a file can be forced, even without actually being
allowed to do anything on the file.

[Arnd Bergmann] include <linux/pagemap.h> for PAGE_CACHE_SIZE (used by
MAX_LFS_FILESIZE definition).
