staging: rtl8192e: Combine three loops to one to init tx_pwr_level_...

The arrays EEPROMRfACCKChnl1TxPwLevel, EEPROMRfAOfdmChnlTxPwLevel,
EEPROMRfCCCKChnl1TxPwLevel, EEPROMRfCOfdmChnlTxPwLevel are initialized to
zero and never changed. The three loops contain the same code. Only the
index of the upper named arrays go from 0 to 2. Therefore the three loops
can be combined to one loop from 0 to 13 which removes useless code.
