dmiller c4a541ac1e Fix IPID sequence detection in the case of Random ...

Reported by Lior Levinsky. As part of r32469, which added IPv6 IPID
sequnce detection, the logic to detect all-zero IPID sequences was
split. get_diffs was returning IPID_SEQ_UNKNOWN, IPID_SEQ_RD, or
1 for all-zeros, but the get_ipid_sequence_* functions were treating
every non-zero return value as indicating all-zeros, which meant that
IPID sequence detection was broken.
