f2fs: compress: fix to cover normal cluster write with cp_rwsem
When we overwrite compressed cluster w/ normal cluster, we should
not unlock cp_rwsem during f2fs_write_raw_pages(), otherwise data
will be corrupted if partial blocks were persisted before CP & SPOR,
due to cluster metadata wasn't updated atomically.
Fixes: 4c8ff7095bef ("f2fs: support data compression")
