xhci: Set quirky xHC PCI hosts to D3 _after_ stopping and freeing them.

PCI xHC host should be stopped and xhci driver memory freed before putting
host to PCI D3 state during PCI remove callback.

Hosts with XHCI_SPURIOUS_WAKEUP quirk did this the wrong way around
and set the host to D3 before calling usb_hcd_pci_remove(dev), which will
access the host to stop it, and then free xhci.
