kernfs: Add support for always empty directories.
commit ea015218f2f7ace2dad9cedd21ed95bdba2886d7 upstream.
Add a new function kernfs_create_empty_dir that can be used to create
directory that can not be modified.
Update the code to use make_empty_dir_inode when reporting a
permanently empty directory to the vfs.
Update the code to not allow adding to permanently empty directories.
