btrfs: zoned: print block-group type for zoned statistics

When printing the zoned statistics, also include the block-group type in
the block-group listing output.

The updated output looks as follows:

 device /dev/vda mounted on /mnt with fstype btrfs
   zoned statistics:
         active block-groups: 9
           reclaimable: 0
           unused: 2
           need reclaim: false
         data relocation block-group: 3221225472
