Fix two SkRecord-backed layer hoisting bugs

Fix two SkRecord-backed layer hoisting bugs

The two bugs are/were:
The old loop to draw the hoisted layers included the saveLayer call which caused double application of the layer's paint (This is the +1 change).

The hoisted layer is intended to be drawn in device coordinates. The old code was drawing it in the coordinate space of the saveLayer thus it was misplaced (This is the setMatrix change).
