This function gets called in rte_mempool_ring.c via the static initialization MACRO MEMPOOL_REGISTER_OPS and exists in librte_mempool_ring.so.  However this library is not loaded when the rte_eal_init() gets called so the static initializers are not yet loaded.

We should just add a better error message if no mempool driver is available.
