[PATCH BlueZ] avdtp: Fix always destroying session immediatelly

[Luiz Augusto von Dentz <luiz.dentz@xxxxxxxxx>]

From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>

In case the remote device sent a close/abort the session shall not be
free immediatelly as the remote may want to reconfigure the stream.
