[ros-diffs] [hbirr] 17248: If the file object is for a device, we must gather some information

If the file object is for a device, we must gather some information 
from the object attribute (at least the OBJ_INHERIT flag). We cannot 
use IoCreateStreamFileObject because a handle from such a file object 
is never inheritable.
