We set WL1271_FLAG_IRQ_RUNNING in the beginning of wlcore_irq(), but clear
it before interrupt handling is done in wlcore_irq_locked().
Let's move the clearing to the end of wlcore_irq() where it gets set,
and remove the old comments about hardirq. That's no longer the case as
we're using request_threaded_irq().
Note that the WL1271_FLAG_IRQ_RUNNING should never race between the
interrupt handler and wlcore_runtime_resume() as because of autosuspend
timeout we cannot enter idle between wlcore_irq_locked() and the end of
wlcore_irq().
