[PATCH 4.14 101/193] 9p: Fix missing commas in mount options

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tuomas Tynkkynen <tuo...@tuxera.com>

commit 61b272c3aa170b3e461b8df636407b29f35f98eb upstream.

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.

Fixes: c4fac9100456 ("9p: Implement show_options")
