Fix panic during Address Resolution of neighbor entry created by NS
When a Neighbor Solicitation is received, a neighbor entry is created with the remote host's link layer address, but without a link layer address resolver. If the host decides to send a packet addressed to the IP address of that neighbor entry, Address Resolution starts with a nil pointer to the link layer address resolver. This causes the netstack to panic and crash. This change ensures that when a packet is sent in that situation, the link layer address resolver will be set before Address Resolution begins.
