### What did you do?

Attempted to list a device path (`\\.\C:`) in Go 1.22 on Windows.

Code, must be ran under admin:

```go
package main

import (
	"log"
	"os"
)

func main() {
	device_path := `\\.\C:`
	f, err := os.Open(device_path)
	if err != nil {
		log.Fatalf("error opening path: %s", err)
	}

	entries, err := f.ReadDir(100)
	if err != nil {
		log.Fatalf("error reading directory: %s", err)
	}

	log.Printf("found %d entries in directory", len(entries))
}
```

Note this also happens for other device paths, not just `\\.\C:`. Other common device paths are things like `\\?\Volume{...}`, `\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy...`, etc. This issue was encountered at https://github.com/kopia/kopia/issues/3842 when dealing with Windows Shadow Copy Volumes in 1.22.

### What did you see happen?

```console
# go version
go version go1.22.4 windows/amd64

# go run main.go
2024/06/04 18:18:10 error reading directory: GetFileInformationByHandleEx \\.\C:: The parameter is incorrect.
```

### What did you expect to see?

This code works as expected in 1.21.10, thus it seems to be a regression.

```console
# go version
go version go1.21.10 windows/amd64

# go run main.go
2024/06/04 18:22:09 found 22 entries in directory
```

In 1.22, you can restore the previous behavior by appending a backslash `\` to the path:

```go
...
device_path := `\\.\C:\` // <- Trailing backslash
...
```

```console
# go version
go version go1.22.4 windows/amd64

# go run main.go 
2024/06/04 18:49:36 found 22 entries in directory
```

but these kinds of paths with trailing backslashes are mangled by functions like `filepath.Clean` and have the backslash stripped. `filepath.Clean` has exceptions for root windows paths like `C:\`, but these exceptions aren't applied to device paths.
