David Hildenbrand 43d746dc49 mm/zsmalloc: use a proper page type ...

Let's clean it up: use a proper page type and store our data (offset into
a page) in the lower 16 bit as documented.

We won't be able to support 256 KiB base pages, which is acceptable. 
Teach Kconfig to handle that cleanly using a new CONFIG_HAVE_ZSMALLOC.

Based on this, we should do a proper "struct zsdesc" conversion, as
proposed in [1].

This removes the last _mapcount/page_type offender.
