s/multi-mempool/multi-rx-mempool/

Also moving argument paragraph up.

With noted issues fixed,
Applied to dpdk-next-net/main, thanks.


Lets wait test report before requesting this to be merged to main repo.

@Yu, @Yuying,

Can you please verify this at the latest head of the next-net tree?

Thanks,
ferruh

Better to move new variable out of packet split related variables, and
below them.
