netfilter: ebtables: Fix argument order to ADD_COUNTER
[ Upstream commit f20faa06d83de440bec8e200870784c3458793c4 ]
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")
