ocfs2: correctly check the return value of ocfs2_search_extent_list
ocfs2_search_extent_list may return -1, so we should check the return value in ocfs2_split_and_insert, otherwise it may cause array index out of bound. And ocfs2_search_extent_list can only return value less than el->l_next_free_rec, so check if it is equal or larger than le16_to_cpu(el->l_next_free_rec) is meaningless.
