Subject: scatterlist: replace flush_kernel_dcache_page with flush_dcache_page
Pages used in scatterlist can be mapped page cache pages (and often are),
so we must use flush_dcache_page here instead of the more limited
flush_kernel_dcache_page that is intended for highmem pages only.
Also remove the PageSlab check given that page_mapping_file as used by the
flush_dcache_page implementations already contains that check.
