This determines the status of a non blocking
UPnP operation. Non blocking UPnP operations return value is an ‘action’
which should be passed to this command.
If an error occurred whilst an action was executing then mnPollUPNP will deal with the error in the usual way (based on the error mode).
Long long int Action: The action that the command should use.
2 if the action is still in progress
0 if the action has been completed
-1 if an error occurred.
