svga: fix invalid memory reference in needs_to_create_zero()
The emit->key.fkey info is only valid if we're generating a fragment shader.
We should not look at it if we're generating a vertex shader.
When generating a vertex shader, the value of emit->key.fkey.num_textures was
garbage and the loop over num_textures would read invalid data. At best
this would cause us to emit an unused constant. At worse, we could segfault.
Just by dumb luck, fkey.num_textures was usually a smallish integer.
NOTE: This is a candidate for the 8.0 branch.
