[PATCH] nfs-utils: add missing comma for exports ent

[Kinglong Mee <kinglongmee@gmail.com>]

When using pnfs with "fsid=0", exportfs prints error as, 

# exportfs -a
exportfs: /var/lib/nfs/etab:1: unknown keyword "no_pnfsfsid=0"

Commit cdd16bef98 ("nfs-utils: add support for the "pnfs" export option")
miss the comma after "pnfs"/"on_pnfs" operation.
