dpdk: don't mask interrupts for some drivers
It is well known that for some NICs, masking
interrupts results in delaying desc writebacks,
which breaks poll mode. This fix introduces an
"int-unmaskable" dpdk device flag to identify such
devices (typically Intel FVL). For such devices,
interrupts are masked by a call to
file_update(...,UNIX_FILE_UPDATE_DELETE) instead
of rte_eth_dev_rx_intr_disable (...)
