This patch is incomplete. I believe qemuProcessStop can be entered even
without any port allocated. If there's a failure at very early phase in
qemuProcessStart, e.g. we fail to get qemu caps or set a hook fails, we
goto cleanup label, where the qemuProcessStop() is called. Hence I think
we should return port only when we allocated it (in which case it is
nonzero). Moreover, not only tlsPort is affected.
