The problem is "q_errors" is available only for Rx queues, and David's patch is
preventing drivers to put Tx error stats into "q_errors" field.

But it is clear that there is a need for a field for Tx queues errors. David has
another patch to using xstats for this. But I believe xstats is making solution
confusing, and now approach is unbalanced for Rx and Tx queues.

I am for adding a new field for Tx queues "q_errors", and this will make getting
stats and David's patch very simple.

The problem with the new fields is it breaks the ABI, but we already increased
the ABIVER for ethdev this release, I believe this is very good timing for this fix.
