qcacld-3.0: Send proper RCL list to upper layer

Host receives channel list via an event
WMI_ROAM_SCAN_CHANNEL_LIST_EVENTID as
getroamscanchannels command response on disconnection.

Host sorts the channel list in descending order before
sending the list to the supplicant. As per current
logic, the host fills only the value of LSB for the
second channel onward. This results in host respond
the RCL list with an invalid format of frequencies
to the upper layer.

Fix is to make sure the host should respond RCL list
with the correct format of frequencies.
