Fix CID 332468: Memory - illegal accesses (UNINIT)

*** CID 332468:  Memory - illegal accesses  (UNINIT)
/lib/dns/zone.c: 6613 in dns_zone_getdnsseckeys()

6613         if (dns_rdataset_isassociated(&keyset)) {
6614             dns_rdataset_disassociate(&keyset);
6615         }

6617             dns_db_detachnode(db, &node);
6618         }

Fix by initializing the 'keyset' with 'dns_rdataset_init'.
