  Log Message:
  Fix seg fault while encoding DHCP domain search option.

Some versions of strtok_r make the original string NULL at the
end of parsing. Adding Null check before ovs_strlcpy() to
prevent segfault in such cases.

Fixes: d79bb92c4b49 ("Add support for DHCP domain search option (119)")
