do_last: kill a rudiment of old ->d_revalidate() workaround
There used to be time when ->d_revalidate() couldn't return an error. So intents code had lookup_instantiate_filp() stash ERR_PTR(error) in nd->intent.open.filp and had it checked after lookup_hash(), to catch the otherwise silent failures. That had been introduced by commit 4af4c52f. These days ->d_revalidate() can and does propagate errors back to callers explicitly, so this check isn't needed anymore.
