sh: Ensure all PG_dcache_dirty pages are written back. With some of the cache rework an address aliasing optimization was added, but this managed to fail on certain mappings resulting in pages with PG_dcache_dirty set never writing back their dcache lines. This patch reverts to the earlier behaviour of simply always writing back when the dirty bit is set.
