[PATCH BlueZ v3] avrcp: Fix unregister AVRCP player

'notify_addressed_player_changed()' expected to be called with
'player->changed_id' set to a non-zero value.

    player->changed_id = g_idle_add(notify_addressed_player_changed,
                                    player);

And 'avrcp_player_event()' relies on 'player->changed_id' to perform
Addressed Player Changed notification. However,
'avrcp_unregister_player()' calls 'notify_addressed_player_changed()'
without adding it to the main loop and set 'player->changed_id'. To
indicate addreddsed player changed for both scenarios, we set
'player->changed_id' to 1 at the head of
'notify_addressed_player_changed()'.
