From: Josef Bacik <josef@xxxxxxxxxxxxxx> commit 1e90315149f3fe148e114a5de86f0196d1c21fa5 upstream. btrfs_assert_delayed_root_empty() will check if the delayed root is completely empty, but this is a filesystem-wide check. On cleanup we may have allowed other transactions to begin, for whatever reason, and thus the delayed root is not empty. So remove this check from cleanup_one_transation(). This however can stay in btrfs_cleanup_transaction(), because it checks only after all of the transactions have been properly cleaned up, and thus is valid.
