i965: Make shader_time use 0 instead of -1 for "no meaningful ID".

Graphics / Mesa 3D Graphics Library / Mesa - Kenneth Graunke [whitecape.org] - 17 April 2015 14:06 UTC

0 is not a valid GLSL shader or ARB program ID. For some reason, shader_time used -1 instead...so we had code to detect 0, then override it to -1.

We can just delete that.
