Bluetooth: Introduce helpers for le conn status and complete
This is done so that the helpers can be used for extended conn implementation which will be done in subsequent patch. Signed-off-by: Jaganath Kanakkassery <jaganathx.kanakkassery@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
