qcacld-3.0: Set freq present as false in sap_get_freq_list
Currently if the first channel if seen in the normalize
acs weight array is found, the driver does not set the
freq present as false back, which leads to further
disabling all frequencies for SAP which should not be
the expectation.
Fix is to set the freq present as false again for the
next frequency.
