[new uImage] rework error handling so common functions don't reset
Changed image_get_ramdisk() to just return NULL on error and have get_ramdisk() propogate that error to the caller. It's left to the caller to call do_reset() if it wants to. Also moved calling do_reset() in get_fdt() and fdt_relocate() on ppc to a common location. In the future we will change get_fdt() and fdt_relocate() to return success/failure and not call do_reset() at all.
