9p: Fix missing commas in mount options
Since commit c4fac9100456 ("9p: Implement show_options"), the mount
options of 9p filesystems are printed out with some missing commas
between the individual options:
p9-scratch on /mnt/scratch type 9p (rw,dirsync,loose,access=clienttrans=virtio)
Add them back.
