cpufreq: Preserve policy's boost state after resume

If the global boost flag was enabled and policy boost flag was disabled
before a suspend resume cycle, cpufreq_online() will enable the policy
boost flag on resume.

While it is important for the policy boost flag to mirror the global
boost flag when a policy is first created, it should be avoided when the
policy is reinitialized (for example after a suspend resume cycle).

Though, if the global boost flag is disabled at this point of time, we
want to make sure policy boost flag is disabled too.
