KUDU-2083. Decrement running maintenance ops on failed prepare

There is currently a bug where we don't decrement the number of
running ops when an op->Prepare() fails. Although rare, when this
bug is hit, it will decrease the number of simultaneous mm ops
that can run until none can, causing the tserver to run OOM.
