own_addr_type 0x01 and 0x03 shall check that a random address has
properly been set and in case of 0x03 the resolving list actually
contains the irk of the identity address:

BLUETOOTH CORE SPECIFICATION Version 5.2 | Vol 4, Part E
page 2596

  'If the advertising set's Own_Address_Type parameter is set to 0x01
  and the random address for the advertising set has not been
  initialized, the Controller shall return the error code Invalid HCI
  Command Parameters (0x12).'

BLUETOOTH CORE SPECIFICATION Version 5.2 | Vol 4, Part E
page 2597

  'If the advertising set's Own_Address_Type parameter is set to 0x03,
  the controller's resolving list did not contain a matching entry, and
  the random address for the advertising set has not been initialized,
  the Controller shall return the error code Invalid HCI Command
  Parameters (0x12).'

v2: Fix checks for Own_Address_Type when is to 0x03 since it can work with
both resolving list _and_ when a random address is set.
