libxfs: bad magic number should set da block buffer error
If xfs_da3_node_read_verify() doesn't recognize the magic number of a buffer it's just read, set the buffer error to -EFSCORRUPTED so that the error can be sent up to userspace. Without this patch we'll notice the bad magic eventually while trying to traverse or change the block, but we really ought to fail early in the verifier. Signed-off-by: Darrick J.
