We can see this app using dd_exit to cleanup. Some error cases: spdk_bdev_get_io_channel failed for -ENOMEM, or it results in dd_open_bdev failed and then dd_exit. For a bdev, dd_exit does cleanup using spdk_put_io_channel. And spdk_put_io_channel allows `ch == NULL`. This causes SEGV. So here add a separate function to check ch, and put cleanup together. This is found by xnvme pre-test.
