libxt_fuzzy: need to account for kernel-level modified variables in .userspacesize

Browse Source 
When reviewing the code, I found there maybe a bug in libxt_fuzzy.c.
If a user wants to delete this match, he will get an error reported,
and the command fails. As the fields after maximum_rate in
xt_fuzzy_mtinfo will be altered in kernel space, we should assign the
userspacesize with the value offsetof(struct xt_fuzzy_mtinfo,
packets_total) instead.
