scsi: lpfc: Replace blk_irq_poll intr handler with threaded IRQ
It has been determined that the threaded IRQ API accomplishes effectively
the same performance metrics as blk_irq_poll. As blk_irq_poll is mostly
scheduled by the softirqd and handled in softirq context, this is not
entirely desired from a Fibre Channel driver context. A threaded IRQ model
fits cleaner. This patch replaces the blk_irq_poll logic with threaded
IRQ.
