RDMA: Pass uverbs_attr_bundle as part of '.reg_user_mr_dmabuf' API

Pass uverbs_attr_bundle as part of '.reg_user_mr_dmabuf' API instead of
udata.

This enables passing some new ioctl attributes to the drivers, as will
be introduced in the next patches for mlx5 driver.

Change the involved drivers accordingly.
