usb: hub: rename khubd to hub_wq in documentation and comments
USB hub has started to use a workqueue instead of kthread. Let's update
the documentation and comments here and there.
This patch mostly just replaces "khubd" with "hub_wq". There are only few
exceptions where the whole sentence was updated. These more complicated
changes can be found in the following files:
