netfilter: x_tables: pass xt_counters struct instead of packet counter
commit 4d31eef5176df06f218201bc9c0ce40babb41660 upstream.
On SMP we overload the packet counter (unsigned long) to contain
percpu offset. Hide this from callers and pass xt_counters address
instead.
Preparation patch to allocate the percpu counters in page-sized batch
chunks.
