MdeModulePkg/UsbBus&XhciDxe: Solve a bug that 2 or more tiers SS hubs with SS devices may have no response.
1.Port reset process may not be proper for some vendor's SS hubs. If the corresponding port shows the reset has been done by C_RESET bit we have to skip the whole reset process for attached devices.
2.Clean C_BH_RESET bit immediately to avoid usb timer entering too many times when 5 tiers hubs are connected.
3.Stop checking URB if there is an error happened.
4.Better error handling for fast hot-plug.
