btrfs_balance_delayed_items is the sole caller of btrfs_wq_run_delayed_node and already includes one of the checks whether the delayed inodes should be run. On the other hand btrfs_wq_run_delayed_node duplicates that check and performs an additional one for wq congestion.
Let's remove the duplicate check and move the congestion one in btrfs_balance_delayed_items, leaving btrfs_wq_run_delayed_node to only care about setting up the wq run. No functional changes.
