Switch ZSWAP_ZPOOL to zsmalloc

Code Issues Proposed changes

The z3fold compressed pages allocator is on it's way
out of the Linux kernel and running this on newer
systems will give you an error:
+ lib/host:configure_zswap:45 : echo z3fold
z3fold
tee: /sys/module/zswap/parameters/zpool: No such file or directory
So, get ahead of things and move to the much faster
recommended by the kernel developers alternative.
