Bluetooth: audio: ascs: Add endpoint by stream lookup function

Browse Source 
This adds endpoint by stream lookup function used to find the active
endpoints that use the stream object provided. The function is used
instead of dereferencing stream->ep that may be not valid if application
did not memset the stream object.
