[S390] Dont check for pfn_valid() in uaccess_pt.c
pfn_valid() actually checks for a valid struct page and not for a valid pfn. Using xip mappings w/o struct pages, this will result in -EFAULT returned by the (page table walk) user copy functions, even though there is valid memory. Those user copy functions don't need a struct page, so this patch just removes the pfn_valid() check.
