[U-Boot] [PATCH 02/16] Revert "image-fit: Fix signature checking"

[Simon Glass]

This reverts commit 84ca65aa4bd0d03867e9e49805201d0564d3ffb0.

On signature verification failures fit_image_verify() should NOT exit with
error. Only keys marked 'required' can cause image verification failure.
This logic is already there and works correctly.

Add a comment to make this clear.
