[dpdk-dev] [PATCH v3] net/tap: fix dev name look-up

Store the device name in dev->data->name, to have symmetrical behavior
between rte_pmd_tap_probe(name) and rte_pmd_tap_remove(name).
The netdevice name (linux interface name) is stored in the name field of
struct pmd_internals.
snprintf(data->name) has been moved closer to the rte_ethdev_allocate()
as it should use the same name.
