Change log from v1:
o relocate F2FS_SET_SB_DIRT to avoid unnecessary checkpoints
The generic_shutdown_super calls sync_filesystem, evict_inode, and then
f2fs_put_super. In f2fs_evict_inode, we remain some dirty inode information
so we should release them at f2fs_put_super.
But normally, it's more reasonable to set its superblock as dirty when
evict_inode is called.
