In the Ubuntu ISO image, it has 0xF8 partition entries. The partition library could not work as expected since it expects the partition entries are no more than 128. Potentially it could have more partition entries, so just remove the check. Signed-off-by: Guo Dong <guo.dong@intel.com> Signed-off-by: Guo Dong <guo.dong@intel.com>
