From: Konstantin Dorfman <kdorfman@xxxxxxxxxxxxxx> When rpmsg client driver destroys last channel endpoint, remove rpmsg device is triggered. In both cases (destroy endpoint and remove device) a glink close command sent to the remote peer. This change, when for removing rpmsg device endpoint already destroyed will avoid sending second glink close command.
