[PATCH v3 1/3] percpu: Fix wrong chunk hints update

[Joonwon Kang]

Chunk end offset was set to a block end offset, which could prevent
chunk hints from being updated correctly. It was observed that the chunk
free size gets minus or shorter than the actual free size due to this.
This commit fixes it.
