common/mlx5: fix build with rdma-core 21

drivers/common/mlx5/mlx5_glue.c: In function 'mlx5_glue_devx_qp_query':
drivers/common/mlx5/mlx5_glue.c:1010:9: error:
implicit declaration of function 'mlx5dv_devx_qp_query'

The function mlx5dv_devx_qp_query() was added in rdma-core 22.
This function is compiled only if HAVE_IBV_DEVX_OBJ,
which is true if the function mlx5dv_devx_obj_create is found.
Unfortunately mlx5dv_devx_obj_create() was introduced in rdma-core 21,
when mlx5dv_devx_qp_query() did not exist yet.

A new flag HAVE_IBV_DEVX_QP is added when mlx5dv_devx_qp_query()
is found.
