revert "initramfs: cleanup incomplete rootfs"
Revert ff1522bb7d9845 ("initramfs: cleanup incomplete rootfs"). Andy reports : This breaks my setup where I have U-boot provided more size of initramfs : than needed. This allows a bit of flexibility to increase or decrease : initramfs compressed image without taking care of bootloader. The proper : solution is to do this if we sure that we didn't get enough memory, : otherwise I can't consider the error fatal to clean up rootfs.
