Bluetooth: hci_event: Fix not checking if HCI_OP_INQUIRY has been sent
Before setting HCI_INQUIRY bit check if HCI_OP_INQUIRY was really sent
otherwise the controller maybe be generating invalid events or, more
likely, it is a result of fuzzing tools attempting to test the right
behavior of the stack when unexpected events are generated.
