irqchip/gic-v5: Remove IRQD_RESEND_WHEN_IN_PROGRESS for ITS IRQs

Lorenzo Pieralisi · KAGA-KOKO · commit 9ba0a63badc8 · 2025-08-05T10:43:48.000+02:00
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.
