netfilter: xt_hashlimit fix

Commit 784544739a25c30637397ace5489eeb6e15d7d49
(netfilter: iptables: lock free counters) broke xt_hashlimit netfilter module :

This module was storing a pointer inside its xt_hashlimit_info, and this pointer
is not relocated when we temporarly switch tables (iptables -L).

This hack is not not needed at all (probably a leftover from
ancient time), as each cpu should and can access to its own copy.
