ZSMALLOC depends on MMU so ZRAM should also depend on MMU since 'select'
does not follow any dependency chains.
Fixes this Kconfig warning:
WARNING: unmet direct dependencies detected for ZSMALLOC
Depends on [n]: MMU [=n]
Selected by [y]:
- ZRAM [=y] && BLK_DEV [=y] && BLOCK [=y] && SYSFS [=y] && (CRYPTO_LZO [=y] || CRYPTO_ZSTD [=m] || CRYPTO_LZ4 [=m] || CRYPTO_LZ4HC [=n] || CRYPTO_842 [=n])
