nvc0/ir: fix textureGather with a single offset
Recent fix for non-const offsets broke the case of a single offset (vs 4
offsets). The later code relies on the offs array to contain null values
to tell whether they should be added onto the srcs list.
Fixes: 5239bd592 ("nvc0/ir: fix overwriting of value backing non-constant gather offset")
