st/nine: Fix bad tracking of bound vs textures

An incorrect formula was used to compute bound_samplers_mask_vs.
Since s is above always 8 for vs and the variable is encoded on 8 bits,
it was always 0.
This resulted in commiting the samplers every call when
there was at least one texture read in the vs shader.
