[PATCH] mm: zswap: fix zswap_never_enabled() for CONFIG_ZSWAP==N

[Barry Song <21cnbao@gmail.com>]

From: Barry Song <v-songbaohua@oppo.com>

If CONFIG_ZSWAP is set to N, it means zswap cannot be enabled.
zswap_never_enabled() should return true.

Fixes: 0300e17d67c3 ("mm: zswap: add zswap_never_enabled()")
