Subject: 9p: Fix missing commas in mount options
X-Git-Tag: v4.19~2112^2

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.
