[dpdk-dev] [PATCH] net/mlx5: fix flow query routine in Direct Verbs

[Slava Ovsiienko <viacheslavo@mellanox.com>]

From: Viacheslav Ovsiienko <Viacheslav Ovsiienko viacheslavo@mellanox.com>

The flow_dv_query() just returns -ENOTSUP value and does not
set provided error parameter structure, that crashes the
port_flow_query(). The patch fixes flow_db_query(), now it
sets an error parameter structure.

Fixes: 684dafe795d0 ("net/mlx5: add flow query abstraction interface")
