f2fs: compress: do sanity check on cluster
This patch adds f2fs_sanity_check_cluster() to support doing
sanity check on cluster of compressed file, it will be triggered
from below two paths:
- __f2fs_cluster_blocks()
- f2fs_map_blocks(F2FS_GET_BLOCK_FIEMAP)
And it can detect below three kind of cluster insanity status.
C: COMPRESS_ADDR
N: NULL_ADDR or NEW_ADDR
V: valid blkaddr
*: any value
1. [*|C|*|*]
2. [C|*|C|*]
3. [C|N|N|V]
