fix incorrect error code mapping for OBJECTID_NOT_FOUND
[ Upstream commit 85f9987b236cf46e06ffdb5c225cf1f3c0acb789 ] It was mapped to EIO which can be confusing when user space queries for an object GUID for an object for which the server file system doesn't support (or hasn't saved one). As Amir Goldstein suggested this is similar to ENOATTR (equivalently ENODATA in Linux errno definitions) so changing NT STATUS code mapping for OBJECTID_NOT_FOUND to ENODATA.
