Allow fake mounts to succeed on non-legacy filesystems.
mountall in Debian depends on being able to pass the -f parameter to
mount, which specifies a fake mount and just updates the mtab. Currently
mount.zfs will fail such a request if it is not passed with -o zfsutil.
This patch allows a fake mount on a non-legacy filesystem to succeed in
the same manner as a -o remount does, thus enabling mountall to work
correctly.
