[XFS] move root inode IRELE into xfs_unmountfs
The root inode is allocated in xfs_mountfs so it should be release in xfs_unmountfs. For the unmount case that means we do it after the the xfs_sync(mp, SYNC_WAIT | SYNC_CLOSE) in the forced shutdown case and the dmapi unmount event. Note that both reference the rip variable which might be freed by that time in case inode flushing has kicked in, so strictly speaking this might count as a bug fix SGI-PV: 981498 SGI-Modid: xfs-linux-melb:xfs-kern:31830a Signed-off-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>
