datapath-windows: changes to existing PACKET_CMD handler.

In this patch we have made following changes:

OvsPacketExecute =>
Changed the data structure to have packet and
actions as pointer (instead of zero length array). It is done because
we will not do memcpy of packet now, pointer will just point
to corresponding offset in input buffer.

OvsExecuteDpIoctl =>
We only need input buffer now. Hence Changed the function signature.
