    fs/fuse/kio: RPC_AFFINITY_RSS to fallthrough to RPC_AFFINITY_RETENT
    
    After revert
     236bfbf16b33b ("Revert "fs/fuse kio: introduce a new rpc affinity mode"")
    
    there is no more RPC_AFFINITY_FAIR_SPREAD and thus fallthrough to
    RPC_AFFINITY_RETENT like it was prior to
    3f286d2b5f406 ("fs/fuse/kio: tidy up RPC_AFFINITY_RSS")
    
    Fixes: 3f286d2b5f406 ("fs/fuse/kio: tidy up RPC_AFFINITY_RSS")
