[dpdk-dev] [PATCH 2/5] net/mlx5: fix secondary process verification

[Nelio Laranjeiro]

Since the secondary process has its own devops, function which cannot be
called by the secondary don't need anymore to verify which process is
calling it.

Fixes: 87ec44ce1651 ("net/mlx5: add operations for secondary process")
