xfs_repair: reinitialize the root directory nlink correctly

In mk_root_dir, we reinitialize the root directory inode with a link
count of 1.  This differs from mkfs parseproto, which initializes the
root to have a link count of 2.  The nlink discrepancy in repair is
caught and corrected during phase 7, but this is unnecessary since we
should set it properly in the first place.
