SCSI: mpt2sas: Fix unsafe using smp_processor_id() in preemptible

commit a2c658505bf5c75516ee0a79287223e86a2474af upstream.

When CONFIG_DEBUG_PREEMPT is enabled, bug is observed in the smp_processor_id().
This is because smp_processor_id() is not called in preempt safe condition.

To fix this issue, use raw_smp_processor_id instead of smp_processor_id.
