Both zram and zswap are used to reduce memory usage by compressing cold page, a default compressor algorithm is selected from kinds of compressor algorithm as the default one from very similar Kconfig, also both of them could change the algorithm by sysfs interfaces, so unify the default compressor algorithm to cleanup the default algorithm chosen.
