xhci: Make roothub functions deal with device removal. Return early in the roothub control and status functions if the xHCI host controller is not electrically present in the system (register reads return all "fs"). This issue only shows up when the xHCI driver registers two roothubs and the host controller is removed from the system. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
