ipoe: fix memory access violation with unset link-selection
Link-selection pointer is not set to NULL when link-selection IPOE
option is not set. It results in a memory access violation in
dhcpv4_packet_insert_opt82()
Set link-selection pointer to NULL if unset to fix the issue.
Fixes: 61e31c591e ("ipoe: add dhcp link selection sub-option")
