commit e83cf875d67a6cb9ddfaa8b45d2fa93d12b5c66f upstream.
Add a xfs_failaddr_t parameter to this function so that callers can potentially pass in (and therefore report) the exact point in the code where we decided that a metadata buffer was corrupt. This enables us to wire it up to checking functions that have to run outside of verifiers.
