Replacing kthread_create, stop and wake_up_process with no-ops is not
always applicable. For example a threaded USB gadget could be ported
by blocking in kthread_run as external events come in via poller.
Allow porting kthread code that way by removing the noop
implementations. The only user is the UBIFS code, so move the
definitions there.
