mesa: Don't call driver RenderTexture for invalid zoffset
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.
v2: Fix off-by-one comparison error noticed by Chris Forbes. Also,
1D_ARRAY textures have Depth == 1. Instead, compare against Height.
