> When a VF port is bound to VFIO-PIC, only miscellaneous interrupt is
> mapped to VFIO vector 0 in eth_ixgbevf_dev_init( ).
> In ixgbevf_dev_start(), if previous VFIO interrupt mapping set in
> eth_ixgbevf_dev_init( ) is not cleard, it will fail when calling rte_intr_enable( )
> tries to map Rx queue interrupt to other VFIO vectors. This patch clears the
> VFIO interrupt mappings before setting both miscellaneous and Rx queue
> interrupt mappings again to avoid failure.
