Subject: [PATCH] btrfs: remove dead assignment to dirid in
 btrfs_search_path_in_tree()

After the introduction of btrfs_search_backwards(), the directory
traversal state in btrfs_search_path_in_tree() is fully maintained via
struct btrfs_key. The local variable 'dirid' is no longer used to control
the search and the assignment

    dirid = key.objectid;

has no observable effect and is dead code.

Remove the unused assignment to avoid confusion and silence static
analysis warnings.

No functional change.
