[PATCH] ethdev: remove dead code in telemetry handler

[PATCH] ethdev: remove dead code in telemetry handler

[Gowrishankar Muthukrishnan]

In telemetry handler for port info, there is no need to check if
eth_dev object of a port id is not null, as it had already been
evaluated once in rte_eth_dev_is_valid_port function.

Fixes: 58b43c1ddfd1 ("ethdev: add telemetry endpoint for device info")
Coverity issue: 373635
