staging: rtl8192e: Remove zeroed arrays tx_pwr_level_cck_a and friends

The arrays tx_pwr_level_cck_a, tx_pwr_level_ofdm_24g_a,
tx_pwr_level_cck_c and tx_pwr_level_ofdm_24g_c are initialized to zero
and never changed. Delete the upper named arrays and set the variables
directly to zero to avoid useless code.
