genirq: Adjust irq thread affinity on IRQ_SET_MASK_OK_NOCOPY return value
irq_move_masked_irq() checks the return code of chip->irq_set_affinity() only for 0, but IRQ_SET_MASK_OK_NOCOPY is also a valid return code, which is there to avoid a redundant copy of the cpumask. But in case of IRQ_SET_MASK_OK_NOCOPY we not only avoid the redundant copy, we also fail to adjust the thread affinity of an eventually threaded interrupt handler. Handle IRQ_SET_MASK_OK (==0) and IRQ_SET_MASK_OK_NOCOPY(==1) return values correctly by checking the valid return values seperately.
