rtnetlink: allocate more memory for dev_set_mac_address()
[ Upstream commit 153711f9421be5dbc973dc57a4109dc9d54c89b1 ]
virtnet_set_mac_address() interprets mac address as struct
sockaddr, but upper layer only allocates dev->addr_len
which is ETH_ALEN + sizeof(sa_family_t) in this case.
We lack a unified definition for mac address, so just fix
the upper layer, this also allows drivers to interpret it
to struct sockaddr freely.
