[PATCH nf] netfilter: ebtables: Fix argument order to ADD_COUNTER

[Todd Seidelmann <tseidelmann@linode.com>]

The ordering of arguments to the x_tables ADD_COUNTER macro
appears to be wrong in ebtables (cf. ip_tables.c, ip6_tables.c,
and arp_tables.c).

This causes data corruption in the ebtables userspace tools
because they get incorrect packet & byte counts from the kernel.

Fixes: d72133e628803 ("netfilter: ebtables: use ADD_COUNTER macro")

My last submission that included Florian Westphal's requests
seems to have been lost in the ether, so I'm resending.
Apologies for the spam.
