[PATCH] xhci: Compute last_ctx from complete set of configured endpoints.

The context entries field of the slot context must be set to one more than the highest endpoint index currently active. The previous logic only included the set of endpoints currently being added, meaning that if an endpoint where dropped then the field would be reset to 1, deactivating all configu
