Good catch, I was wrongly expecting that rte_malloc() functions sets
rte_errno on error.

I wonder if the malloc API shouldn't be modified, because I can see
several places where the same kind of fix would be needed: rte_efd,
rte_cuckoo_hash, rte_fbk_hash, rte_member, ...

Anatoly, what do you think?
