store/tikv: remove WithCancel in copIterator. ( #5701 )
...
Since we already have `finished` channel to make the worker exit, we don't need to select
on `ctx.Done`, instead, we can only select `ctx.Done` in `Next`, and close the `finished` channel.
This avoid the cost to create context by `WithCancel` and select on extra channel.
