[Mesa-stable] [PATCH 1/2] nv50/ir: fix srcMask computation for TG4 and TXF

[Ilia Mirkin]

This affects which inputs are marked as used. In a situation where only
the texture instruction uses an input, it might have been ignored as
unused due to input masks.

Affects subtests of KHR-GL45.texture_cube_map_array.sampling
