ocfs2_defrag_extent() might leak allocated clusters. When the file system has insufficient space, the number of claimed clusters might be less than the caller wants. If that happens, the original code might directly commit the transaction without returning clusters. This patch is based on code in ocfs2_add_clusters_in_btree().
