Stop checking for valid handle in DevInfo.Close()

Browse Source 
User should not have called or deferred the Close() method should
SetupDiGetClassDevsEx() return an error (and invalid handle). And even
if user does that, a SetupDiDestroyDeviceInfoList(INVALID_HANDLE_VALUE)
is harmless. It just returns ERROR_INVALID_HANDLE - we have a unit test
for this in TestSetupDiDestroyDeviceInfoList().
