Log:
  ixl: Fix panic caused by bug exposed by r344062
  
  Don't use a struct if_irq for IFLIB_INTR_IOV type interrupts since that results
  in get_core_offset() being called on them, and get_core_offset() doesn't
  handle IFLIB_INTR_IOV type interrupts, which results in an assert() being triggered
  in iflib_irq_set_affinity().
