Fixes wrong assumption in memcpy length.
ip6_addr_t is >16.

stack.c: In function '_net_init':                                                                    
stack.c:207:5: error: 'memcpy' reading 20 bytes from a region of size 16 [-Werror=stringop-overflow=]           
     memcpy(&local6.addr, local6_a, sizeof(local6));                                                                                         
stack.c: In function '_prepare_send_checks':
stack.c:244:13: error: 'memcpy' reading 20 bytes from a region of size 16 [-Werror=stringop-overflow=]
             memcpy(&nc->next_hop_address, remote6, sizeof(ip6_addr_t));
cc1: all warnings being treated as errors
