This has us use raw_smp_processor_id() in iblock's plug_device callout.
smp_processor_id() is not needed here, because we are running from a per
CPU work item that is also queued to run on a worker thread that is
normally bound to a specific CPU. If the worker thread did end up switching
CPUs then it's handled the same way we handle when the work got moved to a
different CPU's worker thread, where we will just end up sending I/O from
the new CPU.
