From: Johan Hedberg <johan.hedberg@xxxxxxxxx> We can't have hci_chan contribute to the "active" reference counting of the hci_conn since otherwise the connection would never get dropped when there are no more users (since hci_chan would be counted as a user). This patch removes hold() when creating the hci_chan and drop() when destroying it.
