[PATCH] verifiers: Don't return error for deferred image

[Leo Yan]

When boot from menu and the flag GRUB_VERIFY_FLAGS_DEFER_AUTH is set,
grub returns error:

 Booting a command list

 error: verification requested but nobody cares: (hd0,gpt1)/Image.

 Press any key to continue...

In this case, the image should be deferred for authentication, grub
should return the file handle and pass down to later firmware (e.g.
U-Boot, etc) for authentication.

For this purpose, rather than returning error, this patch prints log
and returns file handler.
