False positive G118: context cancellation function not called

[mholt]

I believe this is a false positive as well:

	ctx, cancel := context.WithCancel(tl.ctx)
	
	job := &ActiveJob{ctx: ctx, cancel: cancel, ...}

	go func(job *ActiveJob) {
		defer func() {
			if r := recover(); r != nil {
				logger.Error("panic",
					zap.Any("error", r),
					zap.String("stack", string(debug.Stack())))
			}
		}()

		logger.Info("running",
			zap.Object("job", row),
			zap.String("state", string(row.State)))

		defer job.cancel() // <-- cancel is called reliably here

		// ...
	})(job)

The cancel() function is called reliably. I do not think it merits a lint error.
