own_addr_type 0x01 and 0x03 shall check that a random address has
properly been set:
BLUETOOTH CORE SPECIFICATION Version 5.2 | Vol 4, Part E
page 2496:
'If LE_Scan_Enable is set to 0x01, the scanning parameters'
Own_Address_Type parameter is set to 0x01 or 0x03, and the random
ddress for the device has not been initialized, the Controller shall
return the error code Invalid HCI Command Parameters (0x12).'

'If Enable is set to 0x01, the scanning parameters' Own_Address_Type
parameter is set to 0x01 or 0x03, and the random address for the
device has not been initialized, the Controller shall return the
