    Revert "dm-ploop: support REQ_FUA for data pios"
    
    This reverts commit 90d5bd81cf926ea3aa72233c52dce813aded30bc.
    
    We don't have REQ_FUA in dm-ploop anymore after commit 4e659676652fa
    ("md: mark dm-ploop and dm-qcow2 targets non-fua") so we can revert all
    our REQ_FUA specific handling.
