cpufreq: interactive: don't drop speed if recently at higher load

Apply min_sample_time to the last time the current target speed
was originally requested or re-validated as appropriate for the
current load, not to the time since the current speed was
originally set.  Avoids periodic dips in speed during bursty
loads.

netfilter: qtaguid: initialize a local var to keep compiler happy.

There was a case that might have seemed like new_tag_stat was not
initialized and actually used.
Added comment explaining why it was impossible, and a BUG()
in case the logic gets changed.

cpufreq: interactive: based hispeed bump on target freq, not actual

For systems that set a common speed for all CPUs, checking current
speed here could bypass the intermediate hispeed bump decision for
this CPU when another CPU was already at hispeed.  This could
result in an overly high setting (for all CPUs) in situations
where all CPUs were about to drop to load levels that map to
hispeed or below.

cpufreq: Separate speed target revalidate time and initial set time

Allow speed drop after min_sample_time elapses from last time

current load / input boost.

Allow speed bump after min_sample_time (or above_hispeed_delay)
elapses from the time the current speed was originally set.
