Prevent NULL MDL's from being queued for transmission.

Under conditions of high load and low resources, it was
possible for NDIS (in combination with overlying drivers) to send
NET_BUFFER_LIST structures containing NULL MDL's for transmission.
This resulted in an immediate bugcheck.

This patch prevents NULL MDL's from being sent to XenVif.
