mm, mem-hotplug: fix section mismatch. setup_per_zone_inactive_ratio() should be __meminit.

Commit bce7394a3e ("page-allocator: reset wmark_min and inactive ratio of
zone when hotplug happens") introduced invalid section references.  Now,
setup_per_zone_inactive_ratio() is marked __init and then it can't be
referenced from memory hotplug code.

This patch marks it as __meminit and also marks caller as __ref.
