jbd: check for error returned by kthread_create on creating journal thread
...
If the thread failed to create the subsequent wait_event will hang forever.
This is likely to happen if kernel hits max_threads limit.
Will be critical for virtualization systems that limit the number of tasks
and kernel memory usage within the container.
(akpm: JBD should be converted fully to the kthread API: kthread_should_stop()
and kthread_stop()).
