This workaround passes 1 as scatter_gather_list value to pass the NULL checks for scatter_gather_list while CAPSULE_FLAGS_PERSIST_ACROSS_RESET flag is set (which is introduced lately to align with UEFI specs). Since these flag checks are not implemented in u-boot properly and corstone1000 does not support scatter_gather_list during capsule update, this patch will skip the check only for on-disk capsule update. This will be fixed with new capsule update design.
