btrfs: clean_tree_block should panic on observed memory corruption and return void
The only error condition in clean_tree_block is an accounting bug. Returning without modifying dirty_metadata_bytes and as if the cleaning as been performed may cause problems later so it should panic instead. It should probably be a BUG_ON but we have btrfs_panic now. Signed-off-by: Jeff Mahoney <jeffm@suse.com>
