> 
> Make sure that we free the IRQs in ixgbe_io_error_detected() when
> responding to an PCIe AER error and also restore them when the interface
> recovers from it.
> 
> Previously it was possible to trigger BUG_ON() check in free_msix_irqs() in
> the case where we call ixgbe_remove() after a failed recovery from AER
> error because the inerrupts were not freed.
