[PATCH] usb: host: xhci: Clean up commands when stop endpoint command is timeout

[Baolin Wang]

Since the stop endpoint command is timeout, we will halt the xHCI
controller and issuing the usb_hc_died() to report abnormal shutdown
of a host controller, but before that, we should clean up the command
queue to free commands memory and complete the pending commands.
