- Quit building a useless IO_RESOURCE_REQUIREMENTS_LIST (and leaking memory) in response to IRP_MN_QUERY_RESOURCES

Browse source 
- Actually store the IO_RESOURCE_REQUIREMENTS_LIST in Irp->IoStatus.Information in response to IRP_MN_QUERY_RESOURCE_REQUIREMENTS so the PnP manager can use it (and fixes another memory leak)
