In the event of no pmd cores available on the local numa for
an rxq to be assigned to, a pmd core from a non-local numa is
selected.
If there are more than one non-local numas with pmd cores they
are RR through and checked if they have non-isolated pmds.
When successfully finding a non-local numa with available pmds
for an rxq, that numa was not being stored. It meant if a similar
situation occurred for a subsequent rxq, the same numa would be
selected again.
Store the last numa used when successfully finding a non-local numa
with available pmds, so the numa RR state is kept for subsequent rxqs.
