UPSTREAM: cpu/hotplug: Handle unbalanced hotplug enable/disable
(cherry picked from commit 01b41159066531cc8d664362ff0cd89dd137bbfa)
When cpu_hotplug_enable() is called unbalanced w/o a preceeding
cpu_hotplug_disable() the code emits a warning, but happily decrements the
disabled counter. This causes the next operations to malfunction.
Prevent the decrement and just emit a warning.
