fs/9p: Add fid before dentry instantiation

commit 5441ae5eb3614d3c28f77073370738a2820c88e4 upstream.

d_instantiate marks the dentry positive. So a parallel lookup and mkdir of
the directory can find dentry that doesn't have fid attached. This can result
in both the code path doing v9fs_fid_add which results in v9fs_dentry leak.
