O3: Fix issue w/wbOutstading being decremented multiple times on blocked cache.
If a split load fails on a blocked cache wbOutstanding can be decremented
twice if the first part of the split load succeeds and the second part fails.
Condition the decrementing on not having completed the first part of the load.
