xhci: Fix xhci debugfs NULL pointer dereference in resume from hibernate
Free the virt_device and its debugfs_private member together.
When resuming from hibernate the .free_dev callback unconditionally
freed the debugfs_private member, but could leave virt_device intact.
This triggered a NULL pointer dereference after resume when usbmuxd
sent a USBDEVFS_SETCONFIGURATION ioctl to a device, trying to add a
endpoint debugfs entry to a already freed debugfs_private pointer.
Fixes: 02b6fdc2a153 ("usb: xhci: Add debugfs interface for xHCI driver")
