quicklists: Only consider memory that can be used with GFP_KERNEL

patch 96990a4ae979df9e235d01097d6175759331e88c in mainline.

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.
