[NFC] Avoid mixing signed and unsigned in subhelpers run (#1505)

Browse Source 
Fix a `-Wsign-compare` warning in the `run()` function, which resulted
in many repeated warnings when compiling with `-Wall` due to the many
template instantiations.

Both `clGetKernelSubGroupInfo` queries return a `size_t`, so it is
unclear why the results of these queries were being cast to `int`.
The `dynsc` uses don't seem to work with negative values, so make the
field unsigned.
