[PATCH v2] event/dlb2: fix delayed_pop test in dlb2_selftest

[Rashmi Shetty]

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.

Fixes: a10e8e96865f ("event/dlb2: add delayed token pop logic")
