cpufreq: Force sync policy boost with global boost on sysfs update

Browse Source 
[ Upstream commit 121baab7b88ed865532dadb7ef1aee6e2bea86f5 ]

If the global boost flag is enabled and policy boost flag is disabled, a
call to `cpufreq_boost_trigger_state(true)` must enable the policy's
boost state.

The current code misses that because of an optimization. Fix it.
