xfs: fix xfs_get_extsz_hint for a zero extent size hint
We can easily set the extsize flag without setting an extent size hint, or one that evaluates to zero. Historically the di_extsize field was only used when it was non-zero, but the commit "Cleanup inode extent size hint extraction" broke this. Restore the old behaviour, thus fixing xfsqa 090 with a debug kernel. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Alex Elder <aelder@sgi.com>
