x86/irq: use move_irq_desc() in create_irq_nr()
move_irq_desc() will try to move irq_desc to the home node if
the allocated one is not correct, in create_irq_nr().
( This can happen on devices that are on different nodes that
are using MSI, when drivers are loaded and unloaded randomly. )
v2: fix non-smp build
v3: add NUMA_IRQ_DESC to eliminate #ifdefs
[ Impact: improve irq descriptor locality on NUMA systems ]
