John Keller ff740fb021 [IA64] SN: prevent IRQ retargetting in request_irq() 
With the introduction of the generic affinity autoselector,
irq_select_affinity(), IRQs are now being retargetted,
using a default mask, via the request_irq() path.
This results in all IRQs targetted at CPU 0.

SN Altix assigns affinity in the SN PROM, and does not
expect that to be changed as part of request_irq().

Set the IRQ_AFFINITY_SET flag to prevent
request_irq() from resetting affinity.
