mm: z3fold: remove z3fold
Patch series "mm: zswap: remove z3fold and zbud", v2.
After 2 cycles of deprecating z3fold, remove it as well as zbud (rationale
in specific patches).
This patch (of 2):
Z3fold has been marked as deprecated for 2 cycles and no one complained,
as expected. As there are no known users, remove the code now.
