[PATCH] kthread: remove worker->task self-assignment

[Bradley Morgan <include@grrlz.net>]

From: Bradley Morgan <brads@mainlining.org>

All kthread worker users now create their workers with
kthread_create_worker*(), which sets worker->task before the worker
starts. The self-assignment in kthread_worker_fn() is dead code now.

Remove it.
