Questionable on WMI calls on `CheckForAssignableDevice`

[shiroinekotfs]

In the CheckDevices(), there are lines that call too much WMI calls.

Please take a review. In a case of a Hyper-V cluster, there may be a hundred, or even thousands of PCI devices, with thousands of memory gap zones.

With the current configuration, finding for a loop of that can cause delay, service disruption, connection issue on the client, or even a crash on the WMI system of the server.
