dhcp: fix dhcp_compl_event

Browse Source 
This patch fixes two problems:

1. The lease field in the dhcp_compl_event message can include a list of
vl_api_domain_server_t structs, but no memory is allocated for it.
2. The DNS server address is not copied properly, resulting in wrong IP4
addresses in the event message.

Type: fix
