  Caught by code review, rte_eth_dev_socket_id() returns -1 on error.
The code should behave the same, but still, do not use LCORE_ID_ANY for
something that is not a lcore id.

Fixes: c15c5897340d ("net/bonding: avoid allocating mempool on unknown socket")

Testing against < 0 would probably be more future proof. But if someone 
decides to update rte_eth_dev_socket_id they will hopefully update 
callers as well.

Applied to dpdk-next-net/master, thanks.
