[PATCH v2 2/8] loader/linux: permit NULL argument for argv[] in grub_initrd_load()

[Ard Biesheuvel <ard.biesheuvel@arm.com>]

grub_initrd_load() takes a char *argv[] argument which is only used
when an error occurs, to print the name of the file that caused the
error. In order to be able to split initrd loading from handling the
initrd command, let's permit argv to be NULL, and fall back to the
file names recorded in the file handles.
