tools/power/x86/intel-speed-select: Remove wrong check in set_isst_id()

Browse Source 
struct isst_id *id is a pointer, comparing it with less than zero is wrong.

The check is there to make sure the id->pkg and id->die is set to -1, when
it is illegal or unavailable. Here comparing with MAX_PACKAGE_COUNT and
MAX_DIE_PER_PACKAGE is sufficient.

Hence remove the wrong check.
