mke2fs: make sure bg 0's unused inode count field is zero'ed for mke2fs -S

There was a bug/typo in commit ba9e0afc5 which caused the first block
group (bg #0) to not have its unused inode count field to get set to
zero in the case of mke2fs -S.  This caused inodes in the first block
group to not be recoverable via mke2fs -S.  Oops.
