Subject: [PATCH] selftests/ftrace: Correctly enable event in instance-event.tc

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]

  # of passed:  1
  # of failed:  0
  # of unresolved:  0
  # of untested:  0
  # of unsupported:  0
  # of xfailed:  0
  # of undefined(test bug):  0
