These patches aim to simplify zswap_swapoff() by removing the
unnecessary trees cleanup code. Patch 1 makes sure that the order of
operations during swapoff is enforced correctly, making sure the
simplification in patch 2 is correct in a future-proof manner.

This is based on mm-unstable and v2 of the "mm/zswap: optimize the
scalability of zswap rb-tree" series [1].
