dax: fix a comment in dax_zero_page_range and dax_truncate_page 



The distinction between PAGE_SIZE and PAGE_CACHE_SIZE was removed in

09cbfeaf mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release}
macros

The comments for the above functions described a distinction between
those, that is now redundant, so remove those paragraphs
