    scsi: smartpqi: Fix smp_processor_id() call trace for preemptible kernels

    Correct kernel call trace when calling smp_processor_id() when called in
    preemptible kernels by using raw_smp_processor_id().

    smp_processor_id() checks to see if preemption is disabled and if not,
    issue an error message followed by a call to dump_stack().

    Brief example of call trace:
    kernel:  check_preemption_disabled: 436 callbacks suppressed
    kernel:  BUG: using smp_processor_id() in preemptible [00000000]
             code: kworker/u1025:0/2354
    kernel:  caller is pqi_scsi_queue_command+0x183/0x310 [smartpqi]
    kernel:  CPU: 129 PID: 2354 Comm: kworker/u1025:0
    kernel:  ...
    kernel:  Workqueue: writeback wb_workfn (flush-253:0)
    kernel:  Call Trace:
    kernel:   <TASK>
    kernel:   dump_stack_lvl+0x34/0x48
    kernel:   check_preemption_disabled+0xdd/0xe0
    kernel:   pqi_scsi_queue_command+0x183/0x310 [smartpqi]
