Fix golangci-lint 1.54.2 errors

Ignore this one as the aliasing is OK here:

pkg/cable/wireguard/getconnections.go:66:28:
    G601: Implicit memory aliasing in for loop. (gosec)
        if k, err := keyFromSpec(&con.Endpoint); err == nil {
		                         ^
pkg/netlink/fake/netlink.go:56:2: directive `//nolint:errorlint...` is
   unused for linter "errorlint" (nolintlint)
       //nolint:errorlint // The given error should not be wrapped.
