[PATCH v2 1/2] btrfs: remove dead assignment to dirid in btrfs_search_path_in_tree()

[Burenchev Evgenii]

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 assignment:

    dirid = key.objectid;

no longer affects control flow and is dead code.

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

No functional change.
