    cluster/ec: Don't mark dirty on entry/meta ops in query-info

    We wanted to mark dirty for metadata/entry operations
    whenever query-info is set and info is not yet there because we
    are anyway sending xattrop over the network. But this is causing
    25% regression from 3.8.8 so removing this optimization

    Also fixed two small issues that we didn't find in the previous
    patch
    1) reconfigure failure was sending return value 0 for optimistic-changelog
    2) ec->optimistic_changelog was set to true even before OPTION_INIT
