Repair some flakiness in CheckTargetForConflictsIn.
When we release and reacquire SerializableXactHashLock, we must recheck
whether an R/W conflict still needs to be flagged, because it could have
changed under us in the meantime. And when we release the partition
lock, we must re-walk the list of predicate locks from the beginning,
because our pointer could get invalidated under us.
Bug report #5952 by Yamamoto Takashi. Patch by Kevin Grittner.
