Subject: [PATCH 5.14 088/432] f2fs: turn back remapped address in compressed page endio

From: Daeho Jeong <daehojeong@...gle.com>

[ Upstream commit 4931e0c93e124357308893a3e5e224cbeeabc721 ]

Turned back the remmaped sector address to the address in the partition,
when ending io, for compress cache to work properly.

Fixes: 6ce19aff0b8c ("f2fs: compress: add compress_inode to cache
compressed blocks")
