serial: omap: don't save IRQ flags on hardirq When we're running our hardirq handler, there's not need to disable IRQs with spin_lock_irqsave() because IRQs are already disabled. It also makes no difference if we save or not IRQ flags. Switch over to simple spin_lock/spin_unlock and drop the "flags" variable.
