Use ip_get_data_any, not ip_get_data, in ippackethdrinfo.

Browse Source 
The difference is that ip_get_data_any doesn't require there to be an
upper-layer header at the end of an IPv6 chain. This avoids the message
"BOGUS!  Can't parse supposed IP packet" during -sO -6 scan. The -sO
sends non–upper-layer headers, some even with empty payloads, and so
causes this situation often.
