Subject: [PATCH v2] f2fs: turn back remapped address in compressed page endio

From: Daeho Jeong <[email protected]>

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")
