If initrd_start cpio extraction fails, CONFIG_BLK_DEV_RAM triggers
fallback to initrd.image handling via populate_initrd_image().
The populate_initrd_image() call follows successful extraction of any
built-in cpio archive at __initramfs_start, but currently performs
built-in archive extraction a second time.
Prior to commit b2a74d5f9d446 ("initramfs: remove clean_rootfs"),
the second built-in initramfs unpack call was used to repopulate entries
removed by clean_rootfs(), but it's no longer necessary now the contents
of the previous extraction are retained.
