genirq/affinity: Use default affinity mask for reserved vectors
The reserved vectors at the beginning and the end of the vector space get cpu_possible_mask assigned as their affinity mask. All other non-auto affine interrupts get the default irq affinity mask assigned. Using cpu_possible_mask breaks that rule. Treat them like any other interrupt and use irq_default_affinity as target mask. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Christoph Hellwig <hch@lst.de>
