staging: rtl8192e: Remove unused RF90_PATH_C and ..D for rf3wireOffset

Remove unused priv->phy_reg_def[RF90_PATH_C].rf3wireOffset and
priv->phy_reg_def[RF90_PATH_D].rf3wireOffset.
rf3wireOffset is used in _rtl92e_phy_rf_read and _rtl92e_phy_rf_write
which are used in:
rtl92e_set_rf_reg and rtl92e_get_rf_reg are used in:
rtl92e_set_bandwidth (eRFPath only for 0 and 1)
rtl92e_config_rf (eRFPath only for 0 and 1)
_rtl92e_phy_switch_channel_step (eRFPath only for 0 and 1)
_rtl92e_dm_check_tx_power_tracking_thermal (eRFPath only for 0)
rtl92e_check_bb_and_rf is used in:
rtl92e_config_rf (eRFPath only for 0 and 1)
_rtl92e_bb_config_para_file (eRFPath only for 0)
rtl92e_config_rf_path is used in:
rtl92e_config_rf (eRFPath only for 0 and 1)
