f2fs: clean up structure extent_node
The union in struct extent_node wass only to indicate below fields
struct rb_node rb_node;
union {
struct {
unsigned int fofs;
unsigned int len;
...
...
can be parsed as fields in struct rb_entry, but they were never be
used explicitly before, so let's remove them for cleanup.
