err.Error() never contains "closed"

syscall.Accept returns Errno

And error descriptions are defined in zerros_*_*.go

https://github.com/golang/go/blob/245e95dfabd77f337373bf2d6bb47cd353ad8d74/src/syscall/zerrors_linux_amd64.go#L1358-L1490

cd /usr/local/go/src/syscall
grep closed zerrors_*

output no lines.
