Unset the depth stencil before reset

It looks like the unreleased resource is a INTZ depth stencil texture. The d3d9
refcount is 0, so the app did its job and released it, but it still exists in
wined3d. The logfile confused me a bit, but the only reason to keep the surface
around is if it is currently assigned as depth stencil. This patch unsets the
depth stencil before checking if any D3DPOOL_DEFAULT resources are left.
