util.go: fix gosimple warning 

Fix this warning from gosimple linter:

>	util.go:127:19: S1040: type assertion to the same type: ref.DockerReference() already has type reference.Named (gosimple)
>			if named, ok := ref.DockerReference().(reference.Named); ok {
>					^

Since containers/image commit dfe2fafaa2d702e5a932721aed55b996024051b1
(made in 2017), DockerReference() always return reference.Named type.
