[PATCH 3/9] mm: remove seemingly spurious reclaimability check from laptop_mode gating

[Johannes Weiner]

1d82de618ddd ("mm, vmscan: make kswapd reclaim in terms of nodes")
allowed laptop_mode=1 to start writing not just when the priority
drops to DEF_PRIORITY - 2 but also when the node is unreclaimable.
That appears to be a spurious change in this patch as I doubt the
series was tested with laptop_mode, and neither is that particular
change mentioned in the changelog. Remove it, it's still recent.
