Description

When performing an XHCI evaluate context as part of adding or removing endpoints from the slot context, we need to make sure that we indicate that the slot context is being updated. This is required by the specification. While hardware lets us get away with it often, QEMU does not. This makes a lot of state clearer.

This was tested as part of 9816. Please see 9816 for testing notes.
