inputs.disk skipped sdb drive

### Relevant telegraf.conf

```toml
[[inputs.disk]]
ignore_fs = ["tmpfs", "devtmpfs", "devfs", "overlay", "aufs", "squashfs"]
```

### Logs from Telegraf

```text
This can see the sdb disk:
sudo -u infra-telegraf cat /proc/self/mounts | grep sdb
/dev/sdb1 /data/kafka xfs rw,noatime,attr2,inode64,logbufs=8,logbsize=128k,sunit=256,swidth=512,noquota 0 0

This showing nothing only sda related:
grep 'disk,device=sdb' /tmp/metrics.out

debug log can see sdb:
infra-telegraf --debug --config /etc/infra-telegraf/infra-telegraf.d/infra-base.conf --test |grep sdb|grep disk|grep -v diskio

```

### System info

ubuntu 22.04 with telegraf 1.24.3 or telegraf 1.32.1

### Docker

_No response_

### Steps to reproduce

Just use the above config part and it will not be reported the disk, only diskio for that specific sdb drive.

### Expected behavior

sdb drive should be shown as this command can see it:
sudo -u telegraf cat /proc/self/mounts | grep sdb

### Actual behavior

sdb totally skipped from metrics

### Additional info

_No response_

Start with the inputs.disk entry point and reproduce the difference between --test output and the emitted metrics using the provided ignore_fs configuration. Trace the disk metric filtering for the mounted /dev/sdb1 path; done when the sdb1 filesystem appears in regular output without changing the intended ignored filesystems.
