WARNING: condition with no effect (if branch == else)

Added in 'commit a619d1abe20c ("rtlwifi: rtl8723be: Add new driver")'

889 else
890 rtl8723be_dm_tx_power_track_set_power(hw, BBSWING, 0,
891 index_for_channel);

Can't figure out what the intent of this condition is but it currently has
no effect as if == else and this most likely is not the intent.

I do not know what the correct code should be here, but I will contact the Realtek engineers and get their interpretation. In the meantime, please do not change this code.

Thanks,

Larry
