intel: Allocate hiz in intel_renderbuffer_move_to_temp()

When moving the renderbuffer to a new miptree, we neglected to allocate
the hiz buffer for the new miptree. Oops.

Fixes all Piglit depthstencil-render-miplevels tests from crash to pass on
Sandybridge.

Note: This is a candidate for the 9.1 branch.
