DPL issue in TX_SINGLE_ESB demo

[dozack]

Transmitter enables DPL during initialization of demo app while receiver does not. I am unable to receive any payload in receiver app (TX_SINGLE_ESB). Solution that worked for me was to comment out

nRF24_SetDynamicPayloadLength(nRF24_DPL_ON);

on line 886.
