[PATCH 1/17] cramfs: use read_mapping_page

read_mapping_page_async() is going away, so convert its only user to
read_mapping_page(). This change has not been benchmarked, however, in
order to get real parallelism this wants something completely different,
like __do_page_cache_readahead(), which is not currently exported.
