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.
