Masami Hiramatsu (Google) 0684b1254b tracing/events: Fix to check the simple_tsk_fn creation
[ Upstream commit cda1fbfc53 ]

Sashiko pointed that this sample code does not correctly handle the
failure of thread creation because kthread_run() can return -errno.

Check the simple_tsk_fn is correctly initialized (created) or not.
