Simplify release event logic in DefaultDrmSession

Browse Source 
This is a no-op assuming the class is always used correctly.
When release causes referenceCount to reach zero there can be at most
one EventDispatcher still connected (which is the one that must be
passed to that final release() call), so we can always pass the event
directly to the EventDispatcher passed in to release().
