f2fs: remove entire rb_entry sharing

This is a last part to remove the memory sharing for rb_tree in extent_cache.

This should also fix arm32 memory alignment issue.

[struct extent_node]               [struct rb_entry]
[0] struct rb_node rb_node;        [0] struct rb_node rb_node;
  union {                              union {
    struct {                             struct {
[16]  unsigned int fofs;           [12]    unsigned int ofs;
      unsigned int len;                    unsigned int len;
                                         };
                                         unsigned long long key;
                                       } __packed;
