f2fs: Don't overwrite all types of node to keep node chain

Currently, we enable node SSR by default, and mixed
different types of node segment to do SSR more intensively.
Although reuse warm node is not allowed, warm node chain
will be destroyed by errors introduced by other types
node chain. So we'd better forbid reusing all types
of node to keep warm node chain.
