rx_good_bytes and rx_good_packets statstic is inconsistent when port stopped,ipackets statistic is minus the discard packets but rx_bytes statistic not.
Also,i40e has no statstic of discard bytes, so we have to delete discard packets item from rx_good_packets statstic.
Fixes: 9aace75fc82e ("i40e: fix statistics")

Avoid typo:
fiX -> fix;
statstic -> statistic
And there are some requirements based on the subject and commit log in , such as:
* The summary line should be around 50 characters.
* The text of the commit message should be wrapped at 72 characters.
Please check the doc " doc/guides/contributing/patches.rst" and use " scripts/check-git-log.sh" to help you.

rx_discards is included in imiss. So I think it's better to minus the discard count.

Hi, Wu Jingjing
Thanks for your feedback .I didn't find statistic of discard bytes i40e data sheet,
so I have to delete discard packets item from rx_good_packets statistic.
In other words, we have no way to to minus the discard byte count from rx_good_bytes.
Also I will make some change to meet requirements of commit log and subject.
