qcacld-3.0: Use sw_target_freq to prepare tx_power_env IE

In populate_dot11f_chan_switch_wrapper() host uses channel number to
prepare tx_power_env IE. As channel number is input to
populate_dot11f_tx_power_env(), tx_power_env IE gets wrong values of
max tx power constraints.
Hence input sw_target_freq to populate_dot11f_tx_power_env().
