xhci: Use correct SLOT ID when handling a completed reset device command

The SLOT ID field of a reset device completion event does not reflect the
SLOT ID set in the actual reset device command.

xhci specs 4.6.11 says that xhci sets all other fields of the event TRB to 0.
VIA controllers return SLOT_ID 0, causing a WARN_ON triggered in current code.

Use the SLOT id from the reset devicr command TRB instead

fixes-3.14: remove useless warning

debloat script causes warning on changing qdisc for inactive
interface. I don't like that.
