cpumask: convert lib/smp_processor_id to new cpumask ops
Impact: fix debug_smp_processor_id() for CONFIG_CPUMASK_OFFSTACK=y
The scheduler now uses the new cpumask API, which deals up to
nr_cpumask_bits, whereas the API used NR_CPUS bits.
If CONFIG_CPUMASK_OFFSTACK=y these two are not equal, so the top bits
are undefined. Leading to bug 12518 "BUG: using smp_processor_id() in
preemptible [00000000] code: dellWirelessCtl/..."
The fix is simple: use the modern API in the check.
