There is a similar error in function 'rte_metrics_tel_reg_port_ethdev_to_metrics', can you fix that as well?

Hi Gaurav,
	Thanks for the fix. Few comments inline. Also, please follow contributing guidelines [1].  There is a cheat sheet [2] which is very helpful.

You can return -ENOMEM directly without assigning it to 'ret'

Is there a reason for the above changes? I think they are unrelated to

This does fix the resource leak, but I do think it can be done in a 
simpler way, as shown in the patch I sent to fix the logged coverity issue
for this: https://patchwork.dpdk.org/patch/78052/
I will remove my patch seeing as this patch is fixing the same thing.
