r16409: Fix Klocwork ID's.

1177

In reg_perfcount.c: 1200 1202 1203 1204
In regfio.c: 1243 1245 1246 1247 1251

Jerry, the reg_perfcount and regfio.c ones, can you take a look please? This
is really your code, and I'm not sure I did the right thing to return an
error.

smbcacls.c: 1377
srv_eventlog_nt.c: 1415 1416 1417
srv_lsa_nt.c: 1420 1421
srv_netlog_nt.c: 1429
srv_samr_nt: 1458 1459 1460
