Previously, memif socket hash is always allocated on NUMA socket 0.
If the application is entirely running on another NUMA socket and EAL
--socket-limit prevents memory allocation on NUMA socket 0, memif
creation fails with "HASH: memory allocation failed" error.

This patch allows allocating memif socket hash on any NUMA socket.

looks good to me. cc'ed the memif maintainer.
