Subject: checkpatch: warn on break after goto or return with same tab indentation

Using break; after a goto or return is unnecessary so emit a warning when
the break is at the same indent level.

So this emits a warning on:

	switch (foo) {
	case 1:
		goto err;
		break;
	}

but not on:

	switch (foo) {
	case 1:
		if (bar())
			goto err;
		break;
	}
