Bug Description

Using Fiber v3.0.0-beta.3, I found that my application was logging errors when serving static content where the file didn't exist when using the FiberApp adaptor middleware to convert the app to a http.HandlerFunc interface.

Not a huge issue, but rather a small annoyance.

Example:
2024/09/12 17:19:23 0.001 #0000000100000000 - 0.0.0.0:0<->127.0.0.1:53221 - GET http://localhost:8080/notfound - cannot open file "C:\path\to\file\does\not\exist\notfound": open C:\path\to\file\does\not\exist\notfound: The system cannot find the file specified.

It looks like the fasthttp.RequestCtx is being initialized with a nil logger in adaptor.handlerFunc() causing fasthttp to use the default logger when fasthttp.RequestCtx.Init() is invoked

// New fasthttp Ctx
var fctx fasthttp.RequestCtx
fctx.Init(req, remoteAddr, nil) // <-- Nil logger being provided
if len(h) > 0 {
	// New fiber Ctx
	ctx := app.AcquireCtx(&fctx)
	// Execute fiber Ctx
	err := h[0](ctx)
	if err != nil {
		_ = app.Config().ErrorHandler(ctx, err) //nolint:errcheck // not needed
	}
} else {
	// Execute fasthttp Ctx though app.Handler
	app.Handler()(&fctx)
}

How to Reproduce

Steps to reproduce the behavior:

1. Create a new Fiber App

app := fiber.New()

2. Serve static files

app.Get("/*", static.New("/path/to/static/files")

3. Convert app to http.HandlerFunc

var h http.Handler = adaptor.FiberApp(app)

4. ListenAndServe

server := &http.Server{
    Handler: h,
    Addr: ":8080"
}

panic(server.ListenAndServe())

5. Navigate to something in browser that doesn't exist and view logs i.e. localhost:8080/notexists

Expected Behavior

Expecting the Noop logger to be invoked, leading to no logs being written.

Code Snippet (optional)

package main

import (
	"log"
	"net/http"

	"github.com/gofiber/fiber/v3"
	"github.com/gofiber/fiber/v3/middleware/adaptor"
	"github.com/gofiber/fiber/v3/middleware/static"
)

func main() {
	app := fiber.New()

	// Contains an index.html only
	app.Get("/*", static.New("./templates"))

	var h http.Handler = adaptor.FiberApp(app)

	server := &http.Server{
		Handler: h,
		Addr:    ":8080",
	}

	log.Fatal(server.ListenAndServe())
}
