[Mesa-stable] [PATCH 3/4] mesa: Don't call driver RenderTexture for invalid zoffset

From: Ian Romanick <ian.d.romanick at intel.com>

This fixes the segfault in the 'invalid slice of 3D texture' and
'invalid layer of an array texture' subtests of piglit's fbo-incomplete
test.

The 'invalid layer of an array texture' subtest still fails.
