btrfs-progs: mkfs: add fallback check for signature

Browse Source

The support to recognize a zoned btrfs in util-linux/blkid may take time
to get updated everywhere. Add a fallback check for the signature to
avoid accidental overwrites.

The following will not succeed on a zoned device:

  $ mkfs.btrfs /dev/zoned1
  $ mkfs.btrfs /dev/zoned1
  WARNING: /dev/zoned1 contains zoned btrfs signature but was not detected by blkid, please update
  ERROR: use the -f option to force overwrite of /dev/zoned1
