MdeMdeModulePkg/Usb: Fixed two usb issues 

1.Fix the bug in interface parser logic for usb camera device. Reserve device address if the device doesn’t get disconnected.
2.Some usb 1.1 devices require the context evaluation immediately with actual max packet size after detecting the device max packet size.
