From: Kevan Rehm <kfr@xxxxxxx>
Routine libxfs_umount() did not call libxfs_iput for the m_rootip
inode, so updates made to that inode could be lost. This adds the
missing call, and re-initializes the m_rootip pointer to be null.
Since the root inode reference is now dropped by libxfs_umount(), it
should *not* be dropped in mkfs parseproto().
