nrf/bluetooth: Handle data length update request. 

The Bluetooth link gets disconnected when connecting from a PC after 30-40
seconds.  This commit adds handling of the data length update request.  The
data length parameter pointer is set to NULL in the reply,  letting the
SoftDevice automatically set values and use them in the data length update
procedure.
