[ Upstream commit 526e81b990e53e31ba40ba304a2285ffd098721f ]
The openvswitch module fails initialization when used in a kernel
without IPv6 enabled. nf_conncount_init() fails because the ct code
unconditionally tries to initialize the netns IPv6 related bit,
regardless of the build option. The change below ignores the IPv6
part if not enabled.
Note that the corresponding _put() function already has this IPv6
configuration check.
Fixes: 11efd5cb04a1 ("openvswitch: Support conntrack zone limit")
