[PATCH 5.11 275/329] f2fs: compress: fix to free compress page correctly

[Greg Kroah-Hartman]

From: Chao Yu <yuchao0@xxxxxxxxxx>

[ Upstream commit a12cc5b423d4f36dc1a1ea3911e49cf9dff43898 ]

In error path of f2fs_write_compressed_pages(), it needs to call
f2fs_compress_free_page() to release temporary page.

Fixes: 5e6bbde95982 ("f2fs: introduce mempool for {,de}compress intermediate page allocation")
