Title:
  blkid fails to find btrfs zoned filesystem label or uuid

Status in util-linux package in Ubuntu:
  New

Bug description:
  System Info:

  lsb_release -rd
  Description:  Ubuntu 22.04 LTS
  Release:      22.04

  
  1. Using an HM SMR drive (I used: ST14000NM0007-2G) create a zoned btrfs 
filesystem

  sudo mkfs.btrfs -O zoned -d single -m single -f /dev/sdb -L cf1657839355
  btrfs-progs v5.16.2
  See http://btrfs.wiki.kernel.org for more information.

  Resetting device zones /dev/sdb (52156 zones) ...
  NOTE: several default settings have changed in version 5.15, please make sure
        this does not affect your deployments:
        - DUP for metadata (-m dup)
        - enabled no-holes (-O no-holes)
        - enabled free-space-tree (-R free-space-tree)

  Label:              cf1657839355
  UUID:               5b7d5659-0ed3-45d3-a36b-fb58eeb93f72
  Node size:          16384
  Sector size:        4096
  Filesystem size:    12.73TiB
  Block group profiles:
    Data:             single          256.00MiB
    Metadata:         single          256.00MiB
    System:           single          256.00MiB
  SSD detected:       no
  Zoned device:       yes
    Zone size:        256.00MiB
  Incompat features:  extref, skinny-metadata, no-holes, zoned
  Runtime features:   free-space-tree
  Checksum:           crc32c
  Number of devices:  1
  Devices:
     ID        SIZE  PATH
      1    12.73TiB  /dev/sdb

  2. Try to use LABEL method to mount

  sudo mount LABEL=cf1657839355 cf1657839355
  mount: cf1657839355: can't find LABEL=cf1657839355.

  Expected that LABEL would be found.  I suspect that libblkid is where
  the issue is since this commands returns all of my other block devices
  except for /dev/sdb.

  sudo blkid|grep sdb

  
  It will mount using hard coded device path

  sudo mount /dev/sdb cf1657839355
  df -h /dev/sdb
  Filesystem      Size  Used Avail Use% Mounted on
  /dev/sdb         13T  3.5M   13T   1% /cf1657839355
