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.
