[PATCH] blk-throttle: get rid of wrong initialization of 'limits_changed'

[Namhyung Kim]

When a new group is initialized, we should set @tg->limits_changed
to false instead of setting @td->limits_changed. But @td and @tg
are initialized to zero via kzalloc_node(), there is no need to set
it explicitly. Just get rid of them.
