Btrfs, fix memory leaks in error paths
Stanse found 2 memory leaks in relocate_block_group and __btrfs_map_block. cluster and multi are not freed/assigned on all paths. Fix that. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: linux-btrfs@vger.kernel.org Signed-off-by: Chris Mason <chris.mason@oracle.com>
