x86/irq: remove leftover code from NUMA_MIGRATE_IRQ_DESC
The original feature of migrating irq_desc dynamic was too fragile
and was causing problems: it caused crashes on systems with lots of
cards with MSI-X when user-space irq-balancer was enabled.
We now have new patches that create irq_desc according to device
numa node. This patch removes the leftover bits of the dynamic balancer.
[ Impact: remove dead code ]
