[PATCH] z3fold: remove the unnecessary limit in z3fold_compact_page

[zhongjiang]

From: zhong jiang <zhongji...@huawei.com>

z3fold compact page has nothing with the last_chunks. even if
last_chunks is not free, compact page will proceed.

The patch just remove the limit without functional change.
