[PATCH 1/2] eventdev: fix eth dev ID truncation in telemetry

[Sergei Iashin]

eth_dev_id is declared as int in handle_rxa_get_queue_conf(),
handle_rxa_get_queue_stats(), handle_rxa_queue_stats_reset(), and
handle_rxa_instance_get(), but is implicitly narrowed to uint16_t when
passed to rte_eth_dev_is_valid_port() via
RTE_EVENT_ETH_RX_ADAPTER_PORTID_VALID_OR_GOTO_ERR_RET().
A value like 65535 + N passes validation as N, but is then used as-is as
an array index, causing out-of-bounds access and SIGSEGV.

To reproduce (requires telemetry enabled):
  echo "/eventdev/rxa_queue_conf,0,65536,0" | \
    socat - UNIX-CONNECT:/var/run/dpdk/vpp/dpdk_telemetry.v2,type=5

Result:
  SIGSEGV at handle_rxa_get_queue_conf + 0x34a, faulting address 0x50

This patch changes eth_dev_id from int to uint16_t to avoid truncation.
