net: macb: Use napi_schedule_irqoff() in IRQ handler

For non-PREEMPT_RT kernels, the IRQ handler runs with interrupts
disabled, allowing the use of napi_schedule_irqoff() to save a pair of
local_irq_{save,restore} operations. For PREEMPT_RT kernels,
napi_schedule_irqoff() behaves identically to napi_schedule().
