EcCommunication: Fix DeviceIoControl return value handling

DeviceIoControl returns BOOL, not NTSTATUS. The previous code assigned
the return value to an NTSTATUS variable and checked with NT_SUCCESS(),
which worked by accident but was incorrect.

Check the boolean return directly and use GetLastError() on failure for
proper error reporting.
