util: call for_each_channel completion in original thread



As specified in the doc of spdk_for_each_channel:
```
Once 'fn' has been called on each channel, 'cpl' will be called
on the thread that spdk_for_each_channel was initially called from.
```

Fixes: ff87d29c ("io_channel: Add mechanism to call a function on
each channel")
