xfs: error out if trying to add attrs and anextents > 0
commit 0f352f8ee8412bd9d34fb2a6411241da61175c0e upstream.
We shouldn't assert if somehow we end up trying to add an attr fork to
an inode that apparently already has attr extents because this is an
indication of on-disk corruption. Instead, return an error code to
userspace.
