xhci: Fix null pointer dereference in resume if xhci has only one roothub
In the re-init path xhci_resume() passes 'hcd->primary_hcd' to hci_init(),
however this field isn't initialized by __usb_create_hcd() for a HCD
without secondary controller.
xhci_resume() is called once per xHC device, not per hcd, so the extra
checking for primary hcd can be removed.
Fixes: e0fe986972f5 ("usb: host: xhci-plat: prepare operation w/o shared hcd")
