Subject: [PATCH] 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.
