lib: dhry: fix unstable smp_processor_id(_) usage
When running the in-kernel Dhrystone benchmark with CONFIG_DEBUG_PREEMPT=y: BUG: using smp_processor_id() in preemptible [00000000] code: bash/938 Fix this by not using smp_processor_id() directly, but instead wrapping the whole benchmark inside a get_cpu()/put_cpu() pair. This makes sure the whole benchmark is run on the same CPU core, and the reported values are consistent.
