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 4af4c52f34606bdaab6930a845550c6fb02078a4.  These days
->d_revalidate() can and does propagate errors back to callers
explicitly, so this check isn't needed anymore.
