In sync_dirty_dir_inodes(), remove_dirty_dir_inode() will be called in the callback of filemap_flush to delete and free dirty dir inode entry. But for the freeing inode entry, missed this step after sbumit data bio, and this may lead to a dead loop if these is freeing inode entry in dir_inode_list. So add the delete and free step to fix it.
