Routine Description:
Notification that an OID request has been completed
If this filter sends a request down to a lower layer, and the request is
pended, the FilterOidRequestComplete routine is invoked when the request
is complete. Most requests we've sent are simply clones of requests
received from a higher layer; all we need to do is complete the original
higher request.
However, if this filter driver sends original requests down, it must not
attempt to complete a pending request to the higher layer.
Arguments:
FilterModuleContext - our filter context area
NdisRequest - the completed request
Status - completion status
