[PATCH 1/2] mm: memcontrol: remove dead code from memory_max_write()

[Johannes Weiner <hannes@xxxxxxxxxxx>]

When the reclaim loop in memory_max_write() is ^C'd or similar, we set
err to -EINTR. But we don't return err. Once the limit is set, we
always return success (nbytes). Delete the dead code.
