    sensor_shell: Fix infinite read
    
    sensor read without count/interval/duration is supposed to read just
    one value (set of values).
    If read was executed before with interval specified next execution
    without arguments ends up in infinite reading loop due to complex
    condition.
    
    Now count/interval/duration are reset before parsing arguments so
    code is more deterministic.
