zsfold: Convert zsfold to use the new mount API
Convert the zsfold filesystem to the new internal mount API as the old one
will be obsoleted and removed. This allows greater flexibility in
communication of mount parameters between userspace, the VFS and the
filesystem.
See Documentation/filesystems/mount_api.txt for more information.
