ocfs2: Small refactor of truncate zeroing code
We'll want to reuse most of this when pushing inline data back out to an extent. Keeping this part as a seperate patch helps to keep the upcoming changes for write support uncluttered. The core portion of ocfs2_zero_cluster_pages() responsible for making sure a page is mapped and properly dirtied is abstracted out into it's own function, ocfs2_map_and_dirty_page(). Actual functionality doesn't change, though zeroing becomes optional. We also turn part of ocfs2_free_write_ctxt() into a common function for unlocking and freeing a page array. This operation is very common (and uniform) for Ocfs2 cluster sizes greater than page size, so it makes sense to keep the code in one place.
