netfilter: cttimeout: fix dependency with l4protocol conntrack module
This patch introduces nf_conntrack_l4proto_find_get() and nf_conntrack_l4proto_put() to fix module dependencies between timeout objects and l4-protocol conntrack modules. Thus, we make sure that the module cannot be removed if it is used by any of the cttimeout objects. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
