Nikunj A Dadhania 2ecfaa4a86 usb-ehci: Add ehci handshake ...

After removal of the QTD, the device driver needs to make sure that
the host controller is really done with this QTD, and does not have
any local/cached copy of this. This is achieved by employing a 3-bit
handshake as explained in the echi spec 4.8.2 and Fig 4-10

Also add missing memory barrier.
