cpufreq: interactive: Reset floor_validate_time if busy at max for 100ms

When the interactive governor selects to run at max frequency it doesn't
re-schedule the timer until it hits an idle. This change checks if the CPU
has been continuously busy for last 100ms on hitting an idle start. If yes,
then floor_validate_time is reset so that the CPU stays at max frequency
for at least another 100 ms before stepping down.
This is an important feature for detecting CPU intensive workloads which
require high frequencies for achieving better performance.

cpufreq: interactive: sync freq feature for interactive governor

1) Add load info to cpufreq_interactive_cpuinfo
2) If load on any other online cpu exceeds sync_freq_load_threshold,
   do not allow the frequency to drop below sync_freq

cpufreq: interactive: Remove trace event from idle_start handler

Removed the trace_cpufreq_interactive_idle_start.
Also fix a crash resulting from accessing NULL policy before taking
the pcpu->enable_sem lock. The policy can be NULL if the core is
hotplugged out before the enable_sem lock is taken.

lib/scatterlist: error handling in __sg_alloc_table()

I was reviewing code which I suspected might allocate a zero size SG
table.  That will cause memory corruption.  Also we can't return before
doing the memset or we could end up using uninitialized memory in the
cleanup path.
