drm/i915/selftests: Fix compare functions provided for sorting

Browse Source 
Both cmp_u32 and cmp_u64 are comparing the pointers instead of the value
at those pointers. This will result in incorrect/unsorted list. Fix it
by deferencing the pointers before comparison.

Fixes: 4ba74e53ad ("drm/i915/selftests: Verify frequency scaling with RPS")
Fixes: 8757797ff9 ("drm/i915/selftests: Repeat the rps clock frequency measurement")
