Zhengjun Xing d850c16583 xhci: Fix kernel oops in trace_xhci_free_virt_device 
commit 44a182b9d1 ("xhci: Fix use-after-free in xhci_free_virt_device")
set dev->udev pointer to NULL in xhci_free_dev(), it will cause kernel
panic in trace_xhci_free_virt_device. This patch reimplement the trace
function trace_xhci_free_virt_device, remove dev->udev dereference and
added more useful parameters to show in the trace function,it also makes
sure dev->udev is not NULL before calling trace_xhci_free_virt_device.
This issue happened when xhci-hcd trace is enabled and USB devices hot
plug test. Original use-after-free patch went to stable so this needs so
be applied there as well.
