adapter service function is using RTE_ETH_FOREACH_DEV() macro for
looping through all available eth devices and flushing any pending
buffered packets.
When Traffic Management nodes (vports) are added and deleted dynamically,
there is a possibility of accessing the device info memory beyond the
allocated limit which can result in segfaults. Fixed the logic to
prevent illegal memory access.
