Mathias Krause 309cf37fe2 packet: fix heap info leak in PACKET_DIAG_MCLIST sock_diag interface
Because we miss to wipe the remainder of i->addr[] in packet_mc_add(),
pdiag_put_mclist() leaks uninitialized heap bytes via the
PACKET_DIAG_MCLIST netlink attribute.

Fix this by explicitly memset(0)ing the remaining bytes in i->addr[].
