sparc64: Fix D-cache flushing on swapin from SW devices.
Thanks to tip form ARM folks and Russell King.
If flush_dcache_page() occurs on a swapin it will have a mapping
and we'll try to defer the flush by setting the dirty bit.
But when it hits update_dcache_page() we won't flush because the
page won't have a mapping any more. So remove the mapping
requirement in flush_dcache().
