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
