qcacld-3.0: Don't set SURVEY_INFO_NOISE_DBM when noise floor is zero

Browse source 
Currently host is sending noise floor as 0, even if channel info
event is not received from FW. This is stopping user space derive
noise floor information from other parameters like bandwidth.

To address this, do not set SURVEY_INFO_NOISE_DBM flag if the
noise floor is 0.
