f2fs: assign CURSEG_ALL_DATA_ATGC if blkaddr is valid
mkdir /mnt/test/comp
f2fs_io setflags compression /mnt/test/comp
dd if=/dev/zero of=/mnt/test/comp/testfile bs=16k count=1
truncate --size 13 /mnt/test/comp/testfile
In the above scenario, we can get a BUG_ON.
kernel BUG at fs/f2fs/segment.c:3589!

The reason is we gave CURSEG_ALL_DATA_ATGC to COMPR_ADDR where the
page was set the gcing flag by set_cluster_dirty().
