[dpdk-dev] [PATCH] eal/bsd: fix config creation

[Anatoly Burakov]

The config create function did not store the mem config address in
the shared memconfig structure, so the secondary processes couldn't
map it at the requred address.

Fixes: b149a7064261 ("eal/freebsd: add config reattach in secondary process")
