intel/compiler: ignore per-primitive attrs when calculating flat input mask 

If we say that per-primitive attributes are flat (which is communicated by
3DSTATE_SBE.ConstantInterpolationEnable), GPU freaks out and applies it
to other (non-flat) attributes.

Fixes: be89ea3231 ("intel/compiler: Handle per-primitive inputs in FS")
