To make this consistent with the coding style, could you please format
it as:

	if (status) {
		BT_ERR(...);
		return;
	}

	if (!test_bit(DUP_FILT) || !hdev->discovery_scan_end)
		return;

	timeout = ...;

Shouldn't you also make sure to cancel this delayed work wherever the
code clears the HCI_LE_SCAN flag? (i.e. in hci_event.c)
