Remove references of the previous surface control in ViewRootImpl

Partial revert to fix regression from f7645aa9a968e2da227f1edceaa2b83054b451dd which
kept a strong ref of the old SC used to detect when the SC changed. This meant that during the lifetime of an app it could keep an additional buffer alive.
