Bug in ExResource tests

There are currently 2 failing tests in ExResource group. The reason being that the current implementation of ROS' ERESOURCE is modelled after VISTA. This means that the counter for active shared acquirements is ActiveEntries and not ActiveCount as it is on W2K3. For more information check changelog for revision 33111.

The ideal solution will be to include a runtime check in the tests which detects whether the tests are running in ROS or Windows and act accordingly. Currently the only way I know is rather hacking and inolves checking whether the value of KeUsedSharedData->MinimumLargePages is 0 which it is for ROS.
