ext4: Remove unnecessary wait_event ext4_run_lazyinit_thread()
For some reason we have been waiting for lazyinit thread to start in the ext4_run_lazyinit_thread() but it is not needed since it was jus unnecessary complexity, so get rid of it. We can also remove li_task and li_wait_task since it is not used anymore.
