issue 137 - correct computation of G
G was wrongly computed in some places, not taking into account CQI and RI bits. This commit saves the correct value computed in ulsch_decoding so we can reuse it in ulsch_decoding_data (and the like). Only the file openair1/PHY/LTE_TRANSPORT/ulsch_decoding.c has been checked. If the computation is done somewhere else the problem might still exist.
