Commit afe35cde6 added additional actions to test 33, but forgot
to reset the image between tests. As a result, './check -nbd 33'
fails because the qemu-nbd process from the first half is still
occupying the port, preventing the second half from starting a
new qemu-nbd process. Worse, the failure leaves a rogue qemu-nbd
process behind even after the test fails, which causes knock-on
failures to later tests that also want to start qemu-nbd.
