You should use SCOPE_OBJECT here.

Please add an ANV_DEFINE_HANDLE_CASTS for anv_debug_report_callback and use
anv_debug_report_callback_to_handle here.

You don't need to walk the list here.  You have the callback just do

ANV_FROM_HANDLE(anv_debug_report_callback, callback, _callback);

at the top and then do

list_del(&callback->link);

No search needed.

Maybe call this destroy_debug_cb to be a bit more descriptive?
