fix minor unreachable code caused by t.Fatal

[Abirdcfly]

https://pkg.go.dev/testing#T.Fatalf

Fatalf is equivalent to Logf followed by FailNow.

see https://go.dev/play/p/I6MX-QOTC9n for example:

package main

import (
	"testing"
)

func TestLastIndex(t *testing.T) {
	t.Errorf("first line")
	t.Errorf("second line")
	t.Fatalf("t.Fatalf will cause exit")
	t.Fatalf("so this line cant reach")
}

/* output:
=== RUN   TestLastIndex
    prog.go:8: first line
    prog.go:9: second line
    prog.go:10: t.Fatalf will cause exit
--- FAIL: TestLastIndex (0.00s)
FAIL

Program exited.

Hi @Abirdcfly! I'm not sure why our CI didn't kick off for this PR, but I'm pretty sure the removal of multierror is going to cause a build failure for testing,

nomad/nomad/structs on Abirdcfly/main 
➜ go test
# github.com/hashicorp/nomad/nomad/structs [github.com/hashicorp/nomad/nomad/structs.test]
./structs_test.go:2321:22: undefined: multierror
./structs_test.go:7097:20: undefined: multierror
FAIL	github.com/hashicorp/nomad/nomad/structs [build failed]
