btrfs: optimize balance_level() path reference handling
Instead of incrementing refcount on 'left' node when it's referenced by
path, simply transfer ownership to path and set left to NULL. This
eliminates:
- Unnecessary refcount increment/decrement operations
- Redundant conditional checks for left node cleanup
The path now consistently owns the left node reference when used.
