udf: Call udf_add_free_space() for more blocks at once in udf_free_blocks()
There's no need to call udf_add_free_space() for one block at a time. It saves us noticeable amount of work and yields different result from the original code only if the filesystem is corrupted and bitmap bit is already cleared. In such case counter of free blocks is probably wrong anyways so the change does not matter. Signed-off-by: Jan Kara <jack@suse.cz>
