    fs/fuse kio: move struct krpc_completion to the end of struct krpc_req
    
    Though the flexible array in krpc_completion is never used when embedded
    in struct krpc_req, it's good practive to place flexible array member at
    the end of a struct to avoid any undefined or unexpected behavior.
    
    Fixes: 4da649462a5a4 ("fs/fuse kio: replace zero-length array with flexible array
    syntax")
