Windows: Deny writes/truncation to files w RO attr
If the readonly file attribute is set on a file, refuse to process
writes, truncations or overwrites. The afsd_service will do so
and this can lead to data corruption.
At the same time, writes from the redirector to afsd_service must
not be denied because of the readonly attribute. That check was
performed during the CreateFile. Otherwise, a new file can be
created with the readonly attribute and then not be writable.
