qcacld-3.0: Fix memory allocation for zero channel list

Browse source 
Current driver try allocate memory when number of channel are passed
as zero which will cause memory allocation failure.

As part of the fix, when number of channels comes as zero then driver
shouldn't allocate memory and let the firmware take care of it.
