ethdev: avoid blocking telemetry for link status

Browse Source 
When querying the link status via telemetry interface, we don't want the
client to have to wait for multiple seconds for a reply. Therefore use
"rte_eth_link_get_nowait()" rather than "rte_eth_link_get()" in the
telemetry callback.

Fixes: c190daedb9b1 ("ethdev: add telemetry callbacks")
