queueDirty: Process a StoredValue that is a CommittedViaPrepare but has no durability-context:

bool onlyMarkDeleted = value && mcbp::datatype::is_xattr(v.getDatatype()); 

    if (onlyMarkDeleted) {

        v.markDeleted(delSource);

    } else {

    v.del(delSource);

    // As part of deleting, set committedState to CommittedViaMutation -

    // this is necessary so when we later queue this SV into

    // CheckpoitnManager, if if was previously CommittedViaPrepare it

    // isn't mis-interpreted for a SyncDelete.

    v.setCommitted(CommittedState::CommittedViaMutation);

    }
