[OE-core] [PATCH 6/6] core-image-tiny-initramfs: Fix error message shown after a successful initrd boot

[Alejandro Hernandez]

When booting core-image-tiny-initramfs, since we want to live on initrd,
on purpose, we never find a rootfs image to switch root to,
this causes init to show an error as it would with other images,
this patch replaces the message shown to the user, avoiding confusion
when it was indeed a successful boot.
