  OVN: do not mark ND packets for conntrack in PRE_LB stage

Do not send Neighbor Discovery packets to conntrack module if
load balancing rules have been added to NB db since otherwise
Neighbor Advertisement frames will be discarded by OVN.
In order to reproduce the issue it is enough to add 2 logical ports
to a single logical switch, assign an IPv6 address to each VIF, and
define a load balance rule on the logical switch. After a while the
ping6 from VIF1 to VIF2 will stop since the vm will not receive any NA
packet
