Issue:
`nonblock-statement-body-position` Errors on Correct Code
<!--
This template is for bug reports. If you are reporting a bug, please continue on. If you are here for another reason, please see below:

1. To propose a new rule: http://eslint.org/docs/developer-guide/contributing/new-rules
2. To request a change: http://eslint.org/docs/developer-guide/contributing/changes
3. If you have any questions, please stop by our chatroom: https://gitter.im/eslint/eslint

Note that leaving sections blank will make it difficult for us to troubleshoot and we may have to close the issue.
-->

**Tell us about your environment**

* **ESLint Version:** 3.17.0
* **Node Version:** 7.6.0
* **npm Version:** 4.1.2

**What parser (default, Babel-ESLint, etc.) are you using?**
Default

**Please show your full configuration:**

<!-- Paste your configuration below: -->
```
{
    rules: {
        'nonblock-statement-body-position':  2
    }
}
```

**What did you do? Please include the actual source code causing the issue.**

<!-- Paste the source code below: -->
```js

function blah() {
    if (window.hey) return window.doit({
        asdf: 2,
    });
    return 1;
}
```

**What did you expect to happen?**
No errors.

**What actually happened? Please include the actual, raw output from ESLint.**

`3:21  error  Expected no linebreak before this statement  nonblock-statement-body-position`

Even if the rule doesn't allow expressions that extend onto the next line (which would be a bit of a bummer), the error message doesn't make a whole lot of sense.

Pull request:
Fix: nonblock-statement-body-position multiline error (fixes #8202)
**What is the purpose of this pull request? (put an "X" next to item)**

[x] Bug fix (https://github.com/eslint/eslint/issues/8202)

**What changes did you make? (Give an overview)**

The nonblock-statement-body-position rule is intended to compare the *start* line of a statement with the end line of the previous token. Due to a typo, it was comparing the *end* line of the statement instead, which caused false positives for multiline statements.

**Is there anything you'd like reviewers to focus on?**

Nothing in particular
