Two ideas:
1) Is rbd_finish_aiocb getting this same return value?
2) Perhaps it's an issue with the return value wrapping around with
very large discards. Adding some logging of the return values of each
rados operation in AioCompletion::complete_request() might give us a
clue. These large negative return values are suspicious.
