nilfs2: see state of root dentry for mount check of snapshots
After applied the patch that unified sb instances, root dentry of snapshots can be left in dcache even after their trees are unmounted. The orphan root dentry/inode keeps a root object, and this causes false positive of nilfs_checkpoint_is_mounted function. This resolves the issue by having nilfs_checkpoint_is_mounted test whether the root dentry is busy or not. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
