v9fs_insert uses v9fs_fid_lookup (which also locks the fid) to get the primary fid associated with the dentry and destroys the v9fs_fid struct after removing the file. If another process called v9fs_fid_lookup on the same dentry, it may wait undefinitely for the fid's lock (as the struct is freed). This patch changes v9fs_remove to use a cloned fid, so the primary fid is not locked and freed.
