event/dlb2: fix delayed_pop test in dlb2_selftest

  Number of events scheduled and available for dequeue
after token pop was set to dequeue_depth-1 instead of
dequeue_depth in test_delayed_pop. The expectation is
that all dequeue_depth number of events can be dequeued
once the last event is released.
