Bluetooth: Provide flags parameter direct to mgmt_device_found
Providing the flags parameter directly to mgmt_device_found function
makes the core simpler and more readable. With this it becomes a lot
easier to add new flags in the future.
This also changes hci_inquiry_cache_update to just return that flags
needed for mgmt_device_found since that is its only use for the two
return parameters anyway.
