Handle defer transactions on a detached layer
If a defer transaction is applied on a detached layer, the barrier layer
cannot dequeue its buffer since it incorrectly waits for the detached
layer to commit its dependent pending states. When a layer is detached
we remove all remove sync points. This fix ensures that an already
detached layer does not add any pending states or sync points.
