[PATCH 4/4] IRQ,IA64: normalize return value of chip->irq_set_affinity() method

[Jiang Liu <liuj97@gmail.com>]

Changeset 3b8249e7 has introduced standard return value IRQ_SET_MASK_OK(0) and
IRQ_SET_MASK_OK_NOCOPY(1) for interrupt controller chip's set_irq_affinity()
method. So use IRQ_SET_MASK_OK instead of 0 for consistency.
