btdev: Fix not checking conditions for LE Set Random Address

The spec says LE Set Random Address cannot be used when scan is enabled
or with legacy advertising:

BLUETOOTH CORE SPECIFICATION Version 5.2 | Vol 4, Part E
page 2480

  'If the Host issues this command when any of advertising (created
  using legacy advertising commands), scanning, or initiating are
  enabled, the Controller shall return the error code Command
  Disallowed (0x0C).'
