[IA64-SGI] fix smp_affinity redirection when using CONFIG_PCI_MSI

Redirecting interrupts using smp_affinity on altix does not work on kernels
built with CONFIG_PCI_MSI.  The problem is that move_irq() turns into a noop
if MSI is built in.  This patch calls move_native_irq() instead of move_irq()
to get around that.
