vdpa/octeon_ep: fix IRQ-to-ring mapping in interrupt handler
Look up the IRQ index in oct_hw->irqs instead of assuming
irq - irqs[0]. This supports non-contiguous IRQ numbers and
avoids incorrect ring indexing when irqs[0] is not the base.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
