Darrick J. Wong fe2f9135df xfs: fix wild memcpy access when formatting ondisk rtrefcount btree roots 
LOLLM noticed that the inode btree root formatting methods copy too many
bytes -- there's only one set of keys in node blocks, not two.  This
causes memory corruption of whatever's beyond the buffers.
