Heinrich Schuchardt 56e3b14703 net: don't memcpy to NULL 
In ndisc_receive() 7 bytes are copied from a buffer of size 6 to NULL.

net_nd_packet_mac is a pointer. If it is NULL, we should set it to the
address of the buffer with the MAC address.

Addresses-Coverity-ID: 430974 ("Out-of-bounds access")
Fixes: c6610e1d90 ("net: ipv6: Add Neighbor Discovery Protocol (NDP)")
