tools:iio: free channel-array completely
In iio_utils.c build_channel_array() dynamically allocates the string generic_name in the current iio_channel_info, which doesn't got freed in case of an error. This dynamically allocated channel-array is used by generic_buffer, and needs to be freed on the error/exit path.
