quicklists: Only consider memory that can be used with GFP_KERNEL

Quicklists calculates the size of the quicklists based on the number of
free pages.  This must be the number of free pages that can be allocated
with GFP_KERNEL.  node_page_state() includes the pages in ZONE_HIGHMEM and
ZONE_MOVABLE which may lead the quicklists to become too large causing OOM.
