    selftests/ftrace: Correctly enable event in instance-event.tc
    
    [ Upstream commit f4e4ada586995b17f828c6d147d1800eb1471450 ]
    
    Function instance_set() expects to enable event 'sched_switch', so we
    should set 1 to its 'enable' file.
    
    Testcase passed after this patch:
      # ./ftracetest test.d/instances/instance-event.tc
      === Ftrace unit tests ===
      [1] Test creation and deletion of trace instances while setting an event
      [PASS]
