[ Upstream commit c9f73a2178c12fb24d2807634209559d6a836e08 ]
The handling of connection failures shall be handled by the request completion callback as already done by hci_cs_le_create_conn, also make sure to use hci_conn_failed instead of hci_le_conn_failed as the later don't actually call hci_conn_del to cleanup.
