Check lower bound of cmsg_len.
If passed cm->cmsg_len was below cmsghdr size the experssion:
datalen = (caddr_t)cm + cm->cmsg_len - (caddr_t)data;
would give negative result. However, in practice it would not
result in a crash because the kernel would try to obtain garbage fds
for given process and would error out with EBADF.
