vcl: zero out cmsg for recvmsg API

When msg->msg_controllen is set in recvmsg, the caller wants to receive
additional information about the messages. However, they might not
always be available. In that case, we should clear cmsg since
the caller uses CMSG_NXTHDR which might access uninitialized fields in
cmsg.

Type: fix
