netdev-dpdk: Use uint8_t for port_id.

Currently, signed integer is used for 'port_id' variable and
'-1' as identifier of bad or uninitialized 'port_id'.

This inconsistent with dpdk library and, also, in few cases,
leads to passing '-1' to dpdk functions where uint8_t expected.

Such behaviour doesn't produce any issues, but it's better to
use same type as in dpdk library for consistency.
Introduced 'dpdk_port_t' typedef for better maintainability.

Also, magic number '-1' replaced with DPDK_ETH_PORT_ID_INVALID
macro.
