f2fs: make exit_f2fs_fs more clear
init_f2fs_fs does:
1) f2fs_build_trace_ios
2) init_inodecache
3) create_node_manager_caches
4) create_segment_manager_caches
5) create_checkpoint_caches
6) create_extent_cache
7) kset_create_and_add
8) kobject_init_and_add
9) register_shrinker
10) register_filesystem
11) f2fs_create_root_stats
12) proc_mkdir
exit_f2fs_fs should do cleanup in the reverse order
to make the code more clear.
