What changes were proposed in this pull request?
After #8132, overTarget.borrow(overSize) may trigger a retrying spill. If so, it calls OverAcquire.repay() during the spill procedure, which checks Preconditions.checkState(overTarget.usedBytes() == 0);. However, currently, 0 < overTarget.usedBytes() < overSize. We can remove this precondition in repay(), and only keep the precondition in borrow().
(Fixes: #8268)
