9pfs: fix potential segfault during walk
If the call to fid_to_qid() returns an error, we will call v9fs_path_free()
on uninitialized paths.
It is a regression introduced by the following commit:
56f101ecce0e 9pfs: handle walk of ".." in the root directory
Let's fix this by initializing dpath and path before calling fid_to_qid().
