Perftest: fix OOO_RECV_WRS enablement flow

Enabling the HAVE_MLX5DV and HAVE_OOO_RECV_WRS flags during perftest
compilation leads to an issue when testing non-Mellanox devices.
Specifically, the create_qp function will invoke mlx5dv_query_device,
which is intended for Mellanox devices. This call will cause the test to
terminate prematurely, as third-party devices do not support the mlx5dv
interface
This commit bypass the mlx5dv_query_device if using non-mlnx device.
