datapath-windows: clarify 'portIdHashArray' in the swithc context

Browse Source 
In this patch, we update the documentation for 'portIdHashArray' to
indicate that a vport would exist in this hash table if and only if it
also exists on the Hyper-V switch.

This functionality to implement this semantic will follow in subsequent
patches.
