[libata] sata_nv: s/spin_lock_irqsave/spin_lock/ in irq handler
We don't need to use the heavier spin lock in the irq handler. It's quite possible we can do this in nv_generic_interrupt() as well, but I didn't take the time to pursue that train of thought. Signed-off-by: Jeff Garzik <jeff@garzik.org>
