i965: Fix INTEL_DEBUG=vs for fixed-function/ARB programs.

Since commit 9cee3ff562f3e4b51bfd30338fd1ba7716ac5737, INTEL_DEBUG=vs
has caused a NULL pointer dereference for fixed-function/ARB programs.

In the vec4 generators, "prog" is a gl_program, and "shader_prog" is the
gl_shader_program.  This is different than the FS visitor.
