await_hard_limits() has the following:

    // The pipeline configuration prevents another IO from entering
    // prepare until the prior one exits and clears this.
    ceph_assert(!blocked_io_wake);

The comment is no longer true. I think when I swapped the pipelining to permit concurrent transaction submission (prior to prepare) for different collections, I broke this constraint without noticing. Should be a pretty simple fix.
