Commit b3fbd58fcbb1 ("mm: Kconfig: simplify zswap configuration") made CONFIG_ZSMALLOC only visible when CONFIG_ZSWAP is selected, which makes it impossible to menuconfig zsmalloc-specific features (stats, chain-size, etc.) on systems that use ZRAM but don't have ZSWAP enabled. Make zsmalloc depend on both ZRAM and ZSWAP.
