SurfaceControl: Fix release

Currently we call decStrong causing ~SurfaceControl to be invoked.
If mOwned=true this will cause a reparent to null which is not the
intended behavior of release. We call SurfaceControl#release before
decStrong to fix this. Also we have destroy call destroy to be less
confusing.
