Fuqian Huang 78d4b1327d scsi: lpfc: use spin_lock_irqsave in IRQ context 
As spin_unlock_irq will enable interrupts.
Function lpfc_findnode_rpi is called from
    lpfc_sli_abts_err_handler (./drivers/scsi/lpfc/lpfc_sli.c)
 <- lpfc_sli_async_event_handler
 <- lpfc_sli_process_unsol_iocb
 <- lpfc_sli_handle_fast_ring_event
 <- lpfc_sli_fp_intr_handler
 <- lpfc_sli_intr_handler
 and lpfc_sli_intr_handler is an interrupt handler.

Interrupts are enabled in interrupt handler.  Use
spin_lock_irqsave/spin_unlock_irqrestore instead of spin_(un)lock_irq in
IRQ context to avoid this.
