qcacld-3.0: Add new API hdd_objmgr_get/put_vdev_by_user

Add new hdd_objmgr_get/put_vdev_by_user to include user id(reference
count dbg id) to help identify the ownership of the ref count.
The old hdd_objmgr_get_vdev api is deprecated. And it will be removed
once all of the reference to it replaced by new API.
