i965/fs: Ignore compute shaders in brw_nir_lower_inputs

The commit shown below caused compute shaders to hit the unreachable
in the default of the switch block. Since compute shaders don't have
any inputs, we can make brw_nir_lower_inputs a no-op for CS.

    i965/vs: Map scalar VS input locations properly; avoid tons of MOVs.
