irqchip/loongson-eiointc: Remove explicit interrupt affinity restore on resume

During suspend all CPUs except CPU0 are hot-unpluged and all active
interrupts are migrated to CPU0.

On resume eiointc_router_init() affines all interrupts to CPU0, so the
subsequent explicit interrupt affinity restore is redundant.

Remove it.
