module: try_then_request_module must wait
Since the whole point of try_then_request_module is to retry
the operation after a module has been loaded, we must wait for
the module to fully load.
Otherwise all sort of things start breaking, e.g., you won't
be able to read your encrypted disks on the first attempt.
