fix: config commit --force not work

[CodeRusher]

In the following code snippet, when curveadm.ParseTopology() function returns an error, it will return err.
but if --force=1 option is set, the logic to update the config should continue to execute.

func runCommit(curveadm *cli.CurveAdm, options commitOptions) error {
	// 1) parse cluster topology
	_, err := curveadm.ParseTopology()
	if err != nil && !skipError(err) {
		return err
	}
}

Case:
(1) For example, for the following config, it has syntax errors(a=1), but the config update will still succeed.
(2) But now if you try to update the config(a: 1), it will fail, reporting a parsing error and unable to proceed the update.

  config:
      a=1

@CodeRusher Thanks your contribute. However, the original intention of this option is to skip the check, not to tolerate any configuration.
