Fix for Issue #568

Setting SERVER_PASS to empty value if variable 'VPCFG_Server_disableServerPassword' is true

@JackTheFragger thank you for the PR! I added a comment to the code above.

shellcheck is complaining about accessing VPCFG_Server_disableServerPassword without defining it.

You could reduce the code to something like:

SERVER_PASS=${SERVER_PASS-secret}
if [ "${VPCFG_Server_disableServerPassword:-}" = true ]; then
  SERVER_PASS=""
fi

Where do I define it?

In defaults. At the same point where you made the current changes.
