[SCSI] pm8001: Fix bogus interrupt state flag issue.
Static checker is giving following warning: " error: calling 'spin_unlock_irqrestore()' with bogus flags" The code flow is as shown below: process_oq() --> process_one_iomb --> mpi_sata_completion In 'mpi_sata_completion' the first call for 'spin_unlock_irqrestore()' is with flags=0, which is as good as 'spin_unlock_irq()' ( unconditional interrupt enabling). So for better performance 'spin_unlock_irqrestore()' can be replaced with 'spin_unlock_irq()' and 'spin_lock_irqsave()' can be replaced by 'spin_lock_irq()'.
