zram: fix Kconfig dependency warning

Browse Source 
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])
