conntrackd: use conntrack ID in the cache lookup
This patch adds the conntrack ID to the comparison that is made in
the lookup of entries that are stored in the cache. For old kernels,
this field is set to zero for all entries so this patch does not
make any difference. For recent kernels, this allows to keep two
entries with the same tuple and different IDs: this is possible if
NetlinkEventsReliable is set on. Moreover, this patch is useful to
test the reliable ctnetlink event delivery in 2.6.31 works fine.
