mm: page_alloc: do not treat a zone that cannot be used for dirty pages as "full"
commit 800a1e750c7b04c2aa2459afca77e936e01c0029 upstream.
If a zone cannot be used for a dirty page then it gets marked "full" which
is cached in the zlc and later potentially skipped by allocation requests
that have nothing to do with dirty zones.
