i965/miptree: Delete the layered rendering resolve

We never fast-clear more than the base slice (LOD 0, layer 0) anyway, so
layered rendering without a resolve is always perfectly safe.  Should
this ever change in the future, we'll have to put some sort of resolve
back in but we can cross that bridge when we come to it.
