MdeModulePkg/UsbBusDxe: Fix UsbPortReset might run into recursive loop
UsbSelectConfig will introduce the UsbConnectDriver call.
If this UsbPortReset is happened in the Usb device driver Start() routine and
the device FW can not be recovered by PortReset, the UsbSelectConfig will
introduce the recursive loop.
[Suggested solution]
Since UsbPortReset should not change the Bus Topology, the Reset flow should
only SetAddress and reconfigure the device.
