    gdbus-codegen: avoid error when wrong interface is provided to --annotate
    
    If the interface given cannot be matched, `iface_obj' was left uninitialized and
    the iface_obj == None check would end up crashing:
    
    Traceback (most recent call last):
      File "/usr/bin/gdbus-codegen", line 41, in <module>
        sys.exit(codegen_main.codegen_main())
      File "/usr/lib64/gdbus-2.0/codegen/codegen_main.py", line 175, in codegen_main
        apply_annotations(all_ifaces, opts.annotate)
      File "/usr/lib64/gdbus-2.0/codegen/codegen_main.py", line 146, in apply_annotations
        apply_annotation(iface_list, iface, None, None, None, None, key, value)
      File "/usr/lib64/gdbus-2.0/codegen/codegen_main.py", line 64, in apply_annotation
        if iface_obj == None:
    UnboundLocalError: local variable 'iface_obj' referenced before assignment
