[RFC PATCH 06/10] genirq: Don't mask IRQ within flow handler if IRQ is flow-masked

mask_irq() lets an IRQ with IRQD_IRQ_FLOW_MASKED set be further masked via chip->irq_mask(). This is necessary for unhandled IRQs as we want to keep them masked beyond eoi_irq() (which clears IRQD_IRQ_FLOW_MASKED). This is however not necessary in paths that do end up handling the IRQ and are
