Chengming Zhou 538148f9ba mm/zsmalloc: clarify class per-fullness zspage counts 
We always use insert_zspage() and remove_zspage() to update zspage's
fullness location, which will account correctly.

But this special async free path use "splice" instead of remove_zspage(),
so the per-fullness zspage count for ZS_INUSE_RATIO_0 won't decrease.

Clean things up by decreasing when iterate over the zspage free list.

This doesn't actually fix anything.  ZS_INUSE_RATIO_0 is just a
"placeholder" which is never used anywhere.
