Subject: xhci: Set URB actual length for stopped control transfers

From: Mathias Nyman <[email protected]>

commit 0ab2881a406b9fd46224a3e8253bbc0141b4f844 upstream.

A control transfer that stopped at the status stage incorrectly warned about a "unexpected TRB Type 4", and did not set the transferred actual_length for the URB.

The URB actual_length for control transfers should contain the bytes transferred in the data stage.

Bytes of a partially sent setup stage and missing bytes from status stage should be left out.
