Kees Cook 8e1f74ea02 usercopy: remove page-spanning test for now ...

A custom allocator without __GFP_COMP that copies to userspace has been
found in vmw_execbuf_process[1], so this disables the page-span checker
by placing it behind a CONFIG for future work where such things can be
tracked down later.
