Merge branch 'devx_set_get' into rdma.git for-next

Leon Romanovsky	says:

====================
Be more strict with DEVX get/set operations for the obj_id.
====================

Based on the mlx5-next branch at
     git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux
due to dependencies.

* branch 'devx_set_get':
  RDMA/mlx5: Use strict get/set operations for obj_id
  RDMA/mlx5: Use the correct obj_id upon DEVX TIR creation
  net/mlx5: Expose ifc bits for query modify header
