Log:
[NTOS:PNPMGR]
- Remove an unneeded ExFreePool(DeviceInstance.Buffer); call in IopGetInterfaceDeviceList
because at this point DeviceInstance is not yet initialized. Fixes MSVC build.
- No need to check for DeviceInstance.Buffer being NULL or not (in IopDeviceStatus),
because in case it was NULL the IopCaptureUnicodeString call already failed.
- Add some brackets to conform to code style.
