No Op Command is defined in XHCI spec (4.6.2) and just reports Command Completion Event with Completion Code == Success. Before this commit, No Op Command is not implemented so xHC reports Command Completion Event with Completion Code == TRB Error. This commit fixes this behaviour to report Completion Code correctly.
