Bluetooth: Controller: Fix DLE to check supported rx length



When the Controller is configured to support less than 251
as the supported maximum data length, missing check caused
the Controller to incorrectly re-initialize its rx buffers
causing assert during the DLE procedure. This commit fixes
the procedure to correctly use the supported maximum length
if the peer requests a transmit length that exceeds the
supported receive length.
