[dpdk-dev] [PATCH 2/2] net/mlx5: fix allocation when no memory on device NUMA node

[Olivier Matz <olivier.matz@6wind.com>]

If there is no memory available on the same numa node than the
device, it is preferable to fallback on another socket instead
of failing.

Fixes: 1e3a39f72d5d ("net/mlx5: allocate verbs object into shared memory")
