PATCH 3/3 Bluetooth: Store default and maximum LE data length settings

When the controller supports the LE Data Length Extension feature, the default and maximum data length are read and now stored.

For backwards compatibility all values are initialized to the data length values from Bluetooth 4.1 and earlier specifications.
