[PATCH v2 BlueZ] device: Fix not clearing error on update_bredr_services

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

When trying to loads contents from file using g_key_file_load_from_file
it may cause an error which needs to be cleared since the gerr is
reused, also make sure the file is always created upfront to avoid
having such error when storage has not been initialized.
