Bluetooth: hci_conn: Fix hci_connect_le_sync

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.
