genirq: Teach handle_simple_irq() to resend an in-progress interrupt
It appears that the defect outlined in 9c15eeb5362c4 ("genirq: Allow
fasteoi handler to resend interrupts on concurrent handling") also
affects some other less stellar MSI controllers, this time using
the handle_simple_irq() flow.
Teach this flow about irqd_needs_resend_when_in_progress(). Given
the invasive nature of this workaround, only this flow is updated.
