opencl: check if gpus.kernelname has to be free()'d before setting.

Browse Source 
In this case it doesn't, since the function is only used for config
parsing (I hope). Add the check to prevent a memory leak, just in
case this changes in the future.

TODO: Option parsing functions should really be moved elsewhere and
renamed appropriately, like set_opt_kernel() or config_set_kernel(),
if config parsing is to remain as-is. It will probably change
drastically, so leaving as-is for now.
