mm: Kconfig: fixup zsmalloc configuration

Browse Source 
zsmalloc is not exclusive to zswap.  Commit b3fbd58fcb ("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.
