Bluetooth: Controller: df: Fix missing node_rx release if wrong CTE type

Periodic advertising sync may be created with CTE type filtering
enabled. When received AUX_SYNC_IND, there are HCI_LE_Periodic_-
Advertising_Sync_Established and HCI_LE_Periodic_Advertising_Report
events generated. In case received AUX_SYNC_IND has wrong CTE type,
HCI_LE_Periodic_Advertising_Sync_Established event is generated.
There may not be HCI_LE_Periodic_Advertising_Report event generated.
In this case node_rx, prepared by LLL, was not released in ULL.
It was lost in ull_sync_established_report.
