[PATCH rdma-rc] RDMA/mlx5: Fix query DCT via DEVX

[Leon Romanovsky]

From: Maor Gottlieb <maorg@xxxxxxxxxx>

When executing DEVX command to query QP object, we need to take
the QP type from the mlx5_ib_qp struct which hold the driver specific
QP types as well, such as DC.

Fixes: 34613eb1d2ad ("IB/mlx5: Enable modify and query verbs objects via DEVX")
