kata-deploy: Return exit code for invalid argument

It hangs when invalid arguments are specified.

```bash
kata-deploy-6sr2p:/# /opt/kata-artifacts/scripts/kata-deploy.sh xxx
Action:
* xxx
...
Usage: /opt/kata-artifacts/scripts/kata-deploy.sh [install/cleanup/reset]
ERROR: invalid arguments
...
^C <- hang
```

I changed it to behave the same as when there are no arguments.

```bash
kata-deploy-6sr2p:/# /opt/kata-artifacts/scripts/kata-deploy.sh
Usage: /opt/kata-artifacts/scripts/kata-deploy.sh [install/cleanup/reset]
ERROR: invalid arguments
kata-deploy-6sr2p:/# echo $?
1
```

Fixes: #11068
