mkfs.vfat: fix volume label to be padded with space
...
The specification requires volume label to be space padded.
Latest fsck.vfat will remove the zero padded volume label
as invalid. See also:
https://github.com/dosfstools/dosfstools/issues/172
Make the default label also "NO NAME" which has the special meaning
that label is not set.
