    [ Upstream commit 074fca3a18e7e1e0d4d7dcc9d7badc43b90232f4 ]
    
    Currently, for IB_WR_LOCAL_INV WR, when the next fence is None, the
    current fence will be SMALL instead of Normal Fence.
    
    Without this patch krping doesn't work on CX-5 devices and throws
    following error:
    
    The error messages are from CX5 driver are: (from server side)
    [ 710.434014] mlx5_0:dump_cqe:278:(pid 2712): dump error cqe

    [ 710.434019] krping: cq completion failed with wr_id 0 status 4 opcode 128 vender_err 32
    
    Fixed the logic to set the correct fence type.
