Log Message:
Deal with control transfers better by
- removing the UHCI_PTR_VF flag for the setup and status stages
which means they are scheduled less aggressively. Some devices
appear to require this (blymn@ has one). The flag was
introduced as a performance improvement for bulk transfers.
- Checking for short reads and making sure the status stage runs
if they're encountered.
