`DeviceInformation->DeviceName.Buffer` was already freed via the previous
`FreePool(TargetDeviceName.Buffer);` call,
since `DeviceInformation->DeviceName` was set to `TargetDeviceName` above
in the code. This resulted in a pool double-free, triggering a corruption
of the pool, and a BSoD.
What had to be freed instead, is `DeviceInformation->SymbolicName.Buffer`
that is allocated at the beginning of the function.
