Subject: [PATCH 4.19 30/71] btrfs: tree-checker: fix the error message for transid error

From: Qu Wenruo <wqu@...e.com>

commit f96d6960abbc52e26ad124e69e6815283d3e1674 upstream.

The error message for inode transid is the same as for inode generation,
which makes us unable to detect the real problem.
