f2fs: compress: fix to update isize when overwriting compressed file
[ Upstream commit 944dd22ea4475bd11180fd2f431a4a547ca4d8f5 ]
We missed to update isize of compressed file in write_end() with
below case:
cluster size is 16KB
- write 14KB data from offset 0
- overwrite 16KB data from offset 0
Fixes: 4c8ff7095bef ("f2fs: support data compression")
