Fix defect flagged by Coverity:
*** CID 1599962: Null pointer dereferences (REVERSE_INULL)
/ospf6d/ospf6_intra.c: 775 in ospf6_intra_prefix_lsa_get_prefix_str()
769 {
770 struct ospf6_prefix *prefix = nth_prefix(lsa->header, pos);
771 struct in6_addr in6 = { 0 };
772 char tbuf[16];
773
774 /* ensure buflen >= INET6_ADDRSTRLEN + '/128\0' */
>>> CID 1599962: Null pointer dereferences (REVERSE_INULL)
>>> Null-checking "lsa" suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
775 if (!lsa || !prefix || !buf || buflen < (5 + INET6_ADDRSTRLEN))
776 return NULL;
777
778 memcpy(&in6, OSPF6_PREFIX_BODY(prefix),
779 OSPF6_PREFIX_SPACE(prefix->prefix_length));
780 inet_ntop(AF_INET6, &in6, buf, buflen);
The check for lsa being not-null happens in ospf6_lsdb_show() and
first dereference happens in ospf6_lsa_show_summary()
