Revert "mm: fix 100% CPU kswapd busyloop on unreclaimable nodes"

This reverts commit 19a7db1e2ef38865a704ea4dfd178b02a8026ada which is
c73322d098e4b6f5f0f0fa1330bf57e218775539 upstream. By adding a new field into
struct pglist_data it changes the ABI. Since the problem doesn't seem to
occur often, revert the change for now.
