Bluetooth: verify AMP hci_chan before amp_destroy

      hci_chan can be created in 2 places: hci_loglink_complete_evt() if
it is an AMP hci_chan, or l2cap_conn_add() otherwise. In theory,
Only AMP hci_chan should be removed by a call to
hci_disconn_loglink_complete_evt(). However, the controller might mess
up, call that function, and destroy an hci_chan which is not initiated
by hci_loglink_complete_evt().

This patch adds a verification that the destroyed hci_chan must have
been init'd by hci_loglink_complete_evt().
