xfs: use null daddr for unset first bad log block
xlog_do_recovery_pass() may return before setting first_bad. The caller
must distinguish that case from an error at a valid log block, including
block zero after the log wraps.
Initialize first_bad to XFS_BUF_DADDR_NULL and test it explicitly before
treating the error as a torn write.
Fixes: 7088c4136fa1 ("xfs: detect and trim torn writes during log recovery")
