[PATCH] scsi/mpt2sas: remove unnecesscary preempt requirement for MSIX

[Alex Shi]

smp_processor_id() need used in preempt safe ENV. Otherwise, the
cpu may be preempted and run on other cpus. But here, we don't care much
the specific CPU which handler the MSI, so just replace it by
raw_smp_processor_id() to avoid preempt debug warning.
