Subject: [PATCH 3/3] irqchip/gic-v5: Remove IRQD_RESEND_WHEN_IN_PROGRESS
 for ITS IRQs

GICv5 LPI interrupts have an active state hence they cannot retrigger
while the IRQ is being handled.

Therefore setting IRQD_RESEND_WHEN_IN_PROGRESS for GICv5 ITS
interrupts provides no benefit and it is useless (and confusing),
it solves an issue that cannot happen.

Remove it.
