[U-Boot] [PATCH v2] efi_loader: bootmgr: print a message when loading from BootNext failed

[AKASHI Takahiro]

If a user defines BootNext but not BootOrder and loading from BootNext
fails, you will see only a message like this:
	BootOrder not defined

This may confuse a user. Adding an error message will be helpful.
