S1024: incorrect suggested fix for embedded type #756

This reproduces with Staticcheck 2020.1.4 (built into gopls), go version is go1.14.1 darwin/amd64.

Repro:

package main

import "time"

type embedTime struct {
	time.Time
}

func main() {
	t := embedTime{}
	t.Sub(time.Now())
}

The suggested fix will convert t.Sub(time.Now()) to time.Until(t), which does not compile. The correct fix would be time.Until(t.Time).
