[PATCH] vmscan: avoid bogus throttling

- If max_scan evaluates to zero due to a very small inactive list and high
  `priority' numbers, we don't want to thrlttle yet.

- In balance_pgdat(), we may end up not scanning any pages because all
  zones happened to be above pages_high.  Avoid throttling in this case too.
