[GFS2] Add NULL entry to token table
match_token() was returning garbage data instead of a fail value. This data happened to match a valid option id for an option that required an argument (in this case, lockproto=%s) For match_token() to correctly fail if the option doesn't match any of the tokens, the token table must end with a NULL entry. This patch adds the NULL entry. Signed-off-by: Benjamin E. Marzinski <bmarzins@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
