9p: Uninitialized variable in v9fs_writeback_fid()
If v9fs_fid_lookup_with_uid() fails then "fid" is not initialized.
The v9fs_fid_lookup_with_uid() can't return NULL. If it returns an
error pointer then we can still pass that to clone_fid() and it will
return the error pointer back again.
Fixes: 6636b6dcc3db ("9p: add refcount to p9_fid struct")
