USB: xhci: Remove unused HCD statistics code.
CONFIG_USB_HCD_STAT was used in an abandoned patch to track host controller throughput statistics. Since CONFIG_USB_HCD_STAT will never be defined, remove code that can never run. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
