ext4: Remove unnecessary wait_event ext4_run_lazyinit_thread()

Browse Source 
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.
