The _docs_ say it returns 0 for failure, non-zero for success.
This implementation is looking for <0 as HRESULT failure, and deriving
an Errno from that.
The new tests fail with GetFileSystemType as it was defined, e.g.,
```
--- FAIL: TestGetFSTypeOfValidButAbsentDrive (0.00s)
fs_windows_test.go:41: GetFileSystemType a:\ unexpectedly succeeded
```
when I definitely do not have an A:\ drive.
