[krbdev.mit.edu #7753] krb5-1.11: Bug fix: iprop

[Richard Basch via RT]

I believe this patch applies to all 1.11.x releases, but certainly
manifested itself quite spectacularly with my iprop fixes to allow tree
replication.

 

Anyway, it is possible for a principal deletion event to be applied via
ulog_replay but not fully applied to the ulog (probably because of a lock
failure). Subsequently, when kpropd attempts to re-apply the missing
updates, it may re-attempt a deletion event and fail (add/modify events
work, but deletions can fail). The following patch fixes this.
