usbnet: Fix up 'FLAG_POINTTOPOINT' and 'FLAG_MULTI_PACKET' overlaps.

Browse Source 
USB tethering does not work anymore since 2.6.39-rc2, but it's okay in
-rc1. The root cause is the new added mask code 'FLAG_POINTTOPOINT'
overlaps 'FLAG_MULTI_PACKET'  in  include/linux/usb/usbnet.h, this
causes logic issue in  rx_process(). This patch cleans up the overlap.
