Fixes gcc '-Wunused-but-set-variable' warning:
fs/btrfs/tree-log.c: In function ‘walk_down_log_tree’: fs/btrfs/tree-log.c:2698:6: warning: variable ‘root_owner’ set but not used [-Wunused-but-set-variable] fs/btrfs/tree-log.c: In function ‘walk_up_log_tree’: fs/btrfs/tree-log.c:2793:6: warning: variable ‘root_owner’ set but not used [-Wunused-but-set-variable]
They are never used, and so can be removed.
