Subject[PATCH] usb: xhci: fix unused function warning
Date
xhci_pci_shutdown() function is no longer called outside of the
CONFIG_PM #ifdef section, causing a harmless warning:

drivers/usb/host/xhci-pci.c:524:13: warning: ‘xhci_pci_shutdown’ defined but not used [-Wunused-function]
static void xhci_pci_shutdown(struct usb_hcd *hcd)

This moves the function into the #ifdef to get a clean build again.

Fixes: f2c710f7dca8 ("usb: xhci: only set D3hot for pci device")
