Trac Ticket #359 - Database RUV could mismatch the one in changelog under the stress
https://fedorahosted.org/389/ticket/359
Fix Description:
. Fix for csnplRollUp - was leaking the node data - since
llistRemoveCurrentAndGetNext will detach the current node,
we have to free the data associated with the current node
first, but not the csn, so set that to NULL first
