Terminate hugetlbfs mount argument list

[2.6.25 candidate I believe]

The match_table_t for the mount arguments in hugetlbfs wasn't 
terminated as match_tokens expect. I didn't see a crash just code
audit, but it's still safer to terminate it in case the variables after
that in .data are not NULL.
