f2fs: wake up all waiters in f2fs_submit_discard_endio
There could be more than one waiter waiting discard IO completion, so we
need use complete_all() instead of complete() in f2fs_submit_discard_endio
to avoid hungtask.
Fixes: ec9895add2c5 ("f2fs: don't hold cmd_lock during waiting discard
command")
