kernel - Fix apparent timing race in early usb keyboard polling code

* Fix an apparent timing race where a USB command does not complete
  prior to the poll issued with the command.  Perform another poll
  in a loop to deal with it.

* Problem appears to occur w/ohci's early poll prior to ehci attachment.
