Hmm I may be reading this wrong, but my understanding was that the
suggestion is to synchronously remove all entries of large folios from
zswap when zswap_mthp is disabled. What I am suggesting is to do the
same thing we do in zswap_store() when zswap is disabled.

Anyway, if we are removing the knob this is not relevant anymore.
