Bluetooth: Remove hci_conn_hold/drop from hci_chan

Browse source 
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.
