st/pbo: only use x coord when reading a PIPE_TEXTURE_1D
This fixes the following NIR validation error in the
st/pbo download FS:
vec2 32 ssa_14 = mov ssa_4.xy
vec2 32 ssa_15 = f2i32 ssa_14
vec1 32 ssa_16 = deref_var &tex (uniform sampler1D)
vec4 32 ssa_17 = (float32)txf ssa_16 (texture_deref), ssa_16 (sampler_deref), ssa_15 (coord)
error: nir_src_num_components(instr->src[i].src) == instr->coord_components (../src/compiler/nir/nir_validate.c:839)
With this change, the FS becomes:
vec4 32 ssa_2 = intrinsic load_frag_coord () ()
vec1 32 ssa_3 = f2i32 ssa_2.x
[...]
vec1 32 ssa_9 = deref_var &tex (uniform sampler1D)
vec4 32 ssa_10 = (float32)txf ssa_9 (texture_deref), ssa_9 (sampler_deref), ssa_3 (coord), ssa_0 (lod)
