Staging: pi433: check error after kthread_run()
Error should be checked with IS_ERR after calling kthread_run()
instead of comparing the returned pointer to an int.
Found by sparse warning:
incompatible types for operation (<)
left side has type struct task_struct *tx_task_struct
right side has type int
