mataijcusparse: increase the cut off cuda version number to avoid a bug for unknwon reasons.

Even some cusparse APIs were introduced in cuda-11.3.0, we now use them only after cuda-11.4.0, which was two months younger than 11.3.0.

We met an error (see below) with cuda-11.3.x, but not with cuda versions lower or higher than 11.3. This might be a petsc bug. Using ifdefs,
aijcusparse code takes different paths, making the issue difficult to investigate. So we just increase the cuda version to get away.
