render: don't free blur_kerns_cache when it's not used
blur_kernel_count could be none zero when user set a blur kernel but didn't enable blur. In that case deinit_render will try to free elements of blur_kerns_cache, causing a segfault because blur_kerns_cache is never allocated. Fixes #209 Signed-off-by: Yuxuan Shui <yshuiv7@gmail.com>
