irqbalance uses sysfs attributes to populate its internal database, which is then used to bind the IRQ to the appropriate NUMA node. On a device accepting multiple MSIs and with interrupt remapping enabled, only the first IRQ entry is exported in the "msi_irqs" directory. This results in irqbalance having no clue of the NUMA affinity for the extra IRQs, so it can't bind them to the correct node. Export all MSI interrupts as sysfs attributes when relevant.
