🐛 [Bug]:  Partial config cause race condition

### Bug Description

This works

```go
app.Use(
  logger.New(),
)
```

while this cause race condition:
```go
app.Use(
  logger.New(logger.Config{
	  Format: "${time} | ${pid} | ${locals:requestid} | ${status} | ${latency} | ${method} | ${path}\n",
  }),
)
```

```bash

==================

### How to Reproduce

```go
func main() {
	app := fiber.New()

	// add middlewares
	app.Use(
		logger.New(logger.Config{
			Format: "${time} | ${pid} | ${locals:requestid} | ${status} | ${latency} | ${method} | ${path}\n",
		}),
	)

	api := app.Group("api/v1")
	api.Get("/test", func(c *fiber.Ctx) error {
		return c.SendString("Hello, World 👋!")
	})

	app.Listen(":3000")
}
```

and do
`seq 1 200 | xargs -n1 -P20  curl "http://172.31.240.1:3000/api/v1/test"`
