In swapcache_free_entries(), if swap_info_get_cont() returns NULL, something wrong occurs for the swap entry. But we should still continue to free the following swap entries in the array instead of skip them to avoid swap space leak. This is just problem in error path, where system may be in an inconsistent state, but it is still good to fix it.
