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 interrupt is being handled.

Therefore, setting the IRQD_RESEND_WHEN_IN_PROGRESS flag on LPIs is
pointless, as the situation this flag caters for cannot happen.

Remove it.
