Subject: [PATCH] throttleRecord: write link-status flags for the correct link

special() marked outLinkStat unconditionally in the off-IOC branch even
for a .SINP change, and checkLink() carried caLink/caLinkNc across the
OUT/SINP loop so SINP's status could be written from OUT's connection
state. Select plinkStat per field in special(), and scope caLink/caLinkNc
per loop iteration so each link's status is computed only from its own
link. init_record was already correct and is left untouched.
