Mounting f2fs with following issue:
sanity_check_inode: inode (ino=4827) has unsupported log cluster size: 0, run
fsck to fix
->find_fsync_dnodes
->add_fsync_inode
->f2fs_iget_retry
->f2fs_iget
->do_read_inode
->sanity_check_inode
It is triggered when entering recovery mode after a system crash.
The root cause is 'i_log_cluster_size' is zero in f2fs inode with
F2FS_COMPR_FL flag. It will resulted in mounting failed, and the
filesystem need to be fscked.
We fix it by adding copying compresion information to f2fs inode
page when recover inode page in f2fs_recover_inode_page().
