r8152: fix the checking of the usb speed
When the usb speed of the RTL8152 is not high speed, the USB_DEV_STAT[2:1]
should be equal to [0 1]. That is, the STAT_SPEED_FULL should be equal
to 2.
There is a easy way to check the usb speed by the speed field of the
struct usb_device. Use it to replace the original metheod.
